FAQs

The atom of an element is made up of 4 protons, 5 neutrons and 4 electrons. What are its atomic number and mass number ? ›

The mass number is the sum of protons and neutrons, so it would be 4+5=9 4 + 5 = 9 . Therefore, the atomic number is 4, and the mass number is 9. The atomic number (Z) of an element is the number of protons in its nucleus. In this case, the atom has 4 protons, so its atomic number is 4.

4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.

The mass number will be the sum of the protons as well as neutrons. In this case, it is 4 protons + 5 neutrons = 9. The mass number is usually written as a the superscript to left of the element symbol. Therefore, the correct isotope symbol for the atom with 4 protons, 4 electrons, and 5 neutrons is 9Be.

Since there are 4 protons and 4 electrons in this atom, we know that the atomic number is Z = 4 Z=4 Z=4. Using a periodic table, we see that this corresponds to the element beryllium, which has the atomic symbol Be.

Four protons each contribute a charge of +1 for a total of +4. Five neutrons each contribute a charge of 0 for a total of 0. Three electrons each contribute a charge of -1 for a total of -3. The total electronic charge is +1.

The atomic number of an atom is equal to the number of protons in the nucleus of an atom or the number of electrons in an electrically neutral atom. For example, in a sodium atom, there are 11 electrons and 11 protons. Thus the atomic number of Na atom = number of electrons = number of protons = 11.

Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

Which elements have 4 neutrons? - Quora. As of 2022, bound or pseudo-bound nuclides of H, He, Li, Be, B, C, N, and O have been identified that have four neutrons. The only stable one is Li-7.

Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons.

Sulphur atom has 16 electrons, 16 protons and 16 neutrons.

What does 4 protons make? ›

The chemical element that has four protons in its nucleus is beryllium. If we know the number of protons, determining the element is easy. This is because the number of protons in a nucleus always defines the element of the atom, and the number of protons will always equal the atomic number of the element.

Group 14 elements have four valence electrons and they include Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn), Lead (Pb), and Flerovium (Fl) . Out of these elements, only Carbon and Silicon have the tendency to catenate but catenation is more commonly observed in Carbon due to its smaller size than Silicon.

4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.

Beryllium has 4 protons and 5 neutrons. Beryllium-8 is an isotope of Beryllium which has 4 protons and 4 neutrons. Beryllium-8 is a radionucleide.

Answer and Explanation:

Since this element has 4 protons, it is beryllium (Be). In the periodic table, beryllium can be found above magnesium (Mg; this element has an atomic number of 12).

The Bohr Model for Beryllium (Be) has 4 protons in the nucleus due to the atomic number of Be being 4. The Mass number is 9 which means Beryllium needs 5 neutrons in the nucleus. (Mass number = protons + neutrons, 9 = 4 + n). Beryllium has four electrons to balance the four protons.

Beryllium is the 4^th element on the periodic table because it has 4 protons in its nucleus. The positive protons will attract 4 electrons to surround the nucleus in order to form a neutral atom. With 4 protons and 5 neutrons, most beryllium atoms have an atomic mass of 9 amu.

Beryllium is a chemical element with symbol Be and atomic number 4.

The basic atomic structure with 6 neutrons, 4 electrons, and 4 protons is Beryllium (Be), and it is a neutral atom not an ion. Its mass number is 10 and it has no net charge.
