What group has 3 electrons?
The Group 3A metals have three valence electrons in their highest-energy orbitals (ns2p1). They have higher ionization energies than the Group 1A and 2A elements, and are ionized to form a 3+ charges.
Group 3 is the first group of transition metals in the periodic table. This group is closely related to the rare-earth elements. It contains the four elements scandium (Sc), yttrium (Y), lutetium (Lu), and lawrencium (Lr). The group is also called the scandium group or scandium family after its lightest member.
These electron configurations make helium and neon very stable. Although argon does not technically have a full outer shell, since the 3n shell can hold up to eighteen electrons, it is stable like neon and helium because it has eight electrons in the 3n shell and thus satisfies the octet rule.
Every element in the boron group has three electrons in its outermost shell (so-called valence electrons), and for each element there is a sharp jump in the amount of energy required to remove the fourth electron, reflecting the fact that this electron must be removed from an inner shell.
All group 13 elements have ns2np1 valence electron configurations, and all tend to lose their three valence electrons to form compounds in the +3 oxidation state. The heavier elements in the group can also form compounds in the +1 oxidation state formed by the formal loss of the single np valence electron.
Aluminium is positioned in group 3 of the periodic table because it has three valence electrons in its outermost shell. Group 3, also known as the boron group, consists of the elements boron (B), aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
Elements having three valence electrons are placed in Group . The oxidation state of these elements is by losing three electrons. In the third group, elements are . These elements are soft and their appearance is like silvery-white metals.
So... for the element of LITHIUM, you already know that the atomic number tells you the number of electrons. That means there are 3 electrons in a lithium atom.
Gallium therefore has three valence electrons. Atoms can combine to achieve an octet of valence electrons by sharing electrons.
All elements present in 3rd period contain 3 shells(K,L,M) in which the electrons are distributed.
Which family or group loses 3 electrons?
Most elements in Group 3 lose three electrons to form 3+ ions.
Group 3A metals are other metals. They have three valence electrons in their outermost shell.
The name of the element is aluminium and its is metallic in nature.
Group 13 elements have 3 valence electrons and mostly form cations with a +3 charge.
The group has also gained two collective names, "earth metals" and "triels". The latter name is derived from the Latin prefix tri- ("three") and refers to the three valence electrons that all of these elements, without exception, have in their valence shells.
Aluminum falls in the p block, in which elements have 3 valence electrons in the p orbital and group 13 has a single electron in a subshell.
Why are they called the alkali metals? The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide.
Metalloids have from three to six electrons in their outer energy level. Boron, pictured in the Figure below, is the only metalloid with just three electrons in its outer energy level.
Matt Wilkinson on the extraordinary virtues of element number 3, Lithium.
Most scientists simply regard the transition metals as the elements in the d-block (groups 3-12) on the periodic table. There are total of 38 elements in this group including Cobalt, Nickel, Iron, Rhodium, Gold, Silver, Cooper, Scandium, Titanium, Vanadium, Manganese, Zinc and Mercury.
What are elements in groups 1 to 3 called?
Group 1: Hydrogen and the Alkali Metals. Group 2: The Alkaline Earth Metals. Group 3: Transition Metals. Group 4: Transition Metals. Group 5: Transition Metals.
The three broad categories of elements are metals, nonmetals, and metalloids.
There are 3 electrons, which means the atom has 3 protons, so the element has an atomic number of 3. Looking at the periodic table, lithium has atomic number 3. So this atom is lithium.
Another form of oxygen, ozone (O3), has three atoms, and sulfur (S8) has eight atoms. All elemental molecules are made of atoms of a single element.
Hence, Aluminium(Al) is an element in the third period having three valence electrons.
| Periodic table group | Valence Electrons |
|---|---|
| Group 1 (I) (alkali metals) | 1 |
| Group 2 (II) (alkaline earth metals) | 2 |
| Groups 3-12 (transition metals) | 2* (The 4s shell is complete and cannot hold any more electrons) |
| Group 13 (III) (boron group) | 3 |
Hence the element with 3 valence electrons in its 6p shell is bismuth (Bi).
The element belongs to IIIA group and 3rd period is with atomic number 13 which is aluminium.
The element that belongs to the 3rd period has 3 shells.
How many electrons are in a 3 period?
The third period contains 8 elements because it corresponds to the filling of the 3s and 3p subshells (of the third shell) which take a total of 8 electrons, two in the 3s and 6 in the 3p subshell.
Aluminum loses its three valence electrons to form a cation with a charge of +3: The names of these cations are the same as the metals from which they are formed (see Table 5.7). Transition elements and the metals to their right do not always follow the octet rule; frequently they form more than one cation.
Iron atoms form cations with a charge of +3 by losing 3 electrons and oxygen atoms gain 2 electrons to form an anion with a −2 charge.
Group III A (13) metals form cations with +3 charge.
Thus, the nonmetal which has three electrons in its outermost shell is Boron.
Boron is a metalloid and has 3 electrons in the outermost shell.
The number of outer electrons is the same as the group number. (The noble gases are a bit of a problem here, because they are normally called group 0 rather then group 8. Helium has 2 outer electrons; the rest have 8.) All elements in group 3, for example, have 3 electrons in their outer level.
Lithium has 3 electrons, 4 neutrons and 3 protons.
The third shell holds 18 electrons; 2 in a 3s orbital; 6 in three 3p orbitals; and 10 in five 3d orbitals. The fourth shell holds 32 electrons; 2 in a 4s orbital; 6 in three 4p orbitals; 10 in five 4d orbitals; and 14 in seven 4f orbitals.
Group 15 elements nitrogen and phosphorus form anions carrying 3 units of negative charge. Because, general outermost shell electronic configuration of group 15 elements is ns2 np3. So, to fulfill octet these atoms accept 3 electrons in outermost shell and convert to anions with -3 charge.
What electrons are in group 13?
These elements are found in Group 13 (XIII) of the p block in the Periodic Table of Elements. Aluminum, gallium, indium, and thallium are metallic. They each have three electrons in their outermost shell (a full s orbital and one electron in the p orbital) with the valence electron configuration ns2np1.
These elements are--not surprisingly--located in column 13 of the periodic table. This group includes boron, aluminum, gallium, indium, thallium, and ununtrium (B, Al, Ga, In, Tl, and Uut, respectively). These elements all have three valence electrons.
The element is aluminium. Its valency is 3.
Group 13 is called the boron group, and boron is the only metalloid in this group. The other group 13 elements are metals. Group 14 is called the carbon group. This group contains two metalloids: silicon and germanium.
Thirteen is one of two numbers within the teen numerical range (13–19), along with fifteen, not derived by cardinal numeral (three) and the teen suffix; instead, it is derived from the ordinal numeral (third).
All group 13 elements have fewer valence electrons than valence orbitals, which generally results in delocalized, metallic bonding. With its high ionization energy, low electron affinity, low electronegativity, and small size, however, boron does not form a metallic lattice with delocalized valence electrons.

Three elements – Air, Water & Earth.
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.
For instance, lithium exists as an isotope with 3 neutrons, and as an isotope with 4 neutrons, but it doesn't exist as an isotope with 2 neutrons or as an isotope with 5 neutrons.
Are there only 3 elements?
In the beginning, or at least following the Big Bang more than 14 billion years ago, there was hydrogen, some helium and a little bit of lithium. A grand total of three elements. Today, there are nearly 100 known naturally occurring elements, with hundreds of variants.
The Four Elements. Greek philosophy supposed the Universe to comprise four elements: Fire, Water, Earth, and Air.
Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
The element belongs to the 3rd period and group 1 of the periodic table is Sodium (Na) having atomic number 11.
The groups 3 to 12 constitute the d-block. The elements belonging to this block are called transition elements.
This group is sometimes called the vanadium group or vanadium family after its lightest member; however, the group itself has not acquired a trivial name because it belongs to the broader grouping of the transition metals. Group 5 in the periodic table. Hydrogen. Helium. Lithium.
Lr. Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Lr. Group 6A (or VIA) of the periodic table are the chalcogens: the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po). The name "chalcogen" means "ore former," derived from the Greek words chalcos ("ore") and -gen ("formation").
