How many neutrons are in carbon?
Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.
Carbon-11 has 6 protons and 5 neutrons, while Carbon-13 has 6 protons and 7 neutrons.
Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12.

To find the number of neutrons, subtract the number of protons from the mass number.
The symbol for magnesium is . Magnesium has an atomic number of 12 and a mass number of 24. So a magnesium atom has 12 protons, 12 electrons, and 12 neutrons.
Carbon-12 is particularly important because it serves as the reference point for determining the atomic masses of all nuclides; the atomic mass is, by definition, precisely 12 daltons. Carbon-12 has six protons, six neutrons, and six electrons. The mass of an atom is its atomic mass.

The next heaviest carbon isotope, carbon-13 (13C), has seven neutrons. Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 (14C) isotope contains eight neutrons in its nucleus. Unlike 12C and 13C, this isotope is unstable, or radioactive.
Carbon-11 is an unstable isotope that has a short half-life of 20.4 min. This radioisotope decays to stable boron-11 predominantly by positron emission (99.79%) and to a very low extent by electron capture (0.21%).
Oxygen atom has 8 electrons, 8 protons and 8 neutrons.
If it has 7 protons, that's nitrogen.

| 7 | N | Nitrogen |
| 8 | O | Oxygen |

Answer and Explanation: Silicon has 14 protons and 14 neutrons. Silicon's atomic number is 14, which tells us that it has 14 protons. It has an atomic mass of 28.

A neutron is made of 3 quarks, one up quark, and 2 down quarks and many many "intermediate particles" called gluons which carry the interaction between the quarks. These gluons are exchanged very often, so the quarks feel each of other. Neutrons do not always decay.
What is 1 neutron?
It is defined as that force necessary to provide a mass of one kilogram with an acceleration of one metre per second per second. One newton is equal to a force of 100,000 dynes in the centimetre-gram-second (CGS) system, or a force of about 0.2248 pound in the foot-pound-second (English, or customary) system.
The mass of a neutron is roughly equal to 1.008 atomic mass units. When converted into kilograms, the mass of the neutron can be approximated to 1.674*10-27 kg.
Carbon is the only element that satisfies the requirements of having four neutrons, three electrons, and three protons.
Why use 12 grams? This is the theoretical atomic mass of the Carbon-12 isotope (6 protons and 6 neutrons). This means that the atomic mass or atomic weight (12 grams) of carbon is equal to exactly 1 mole of carbon.
It is a stable form with six protons and seven neutrons. There also is a Carbon 14, which has six protons and eight neutrons. Carbon 14 occurs in very small quantities in the environment, with about one Carbon 14 atom for every trillion Carbon 12 atoms.
Recall that there is much, much more 12C than 13C in the world –almost 99% of all carbon atoms are 12C. Even so, different carbon pools have different ratios of 13C and 12C – called isotopic fingerprints.
They are non-toxic, non-flammable gases that contain carbon, chlorine, and fluorine.
Carbon-14 is a weakly radioactive isotope of Carbon; also known as radiocarbon, it is an isotopic chronometer.
Carbon-14, C-14, C or radiocarbon, is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
Caesium as 55 protons and 78 neutrons in its nucleus giving it an Atomic Number of 55 and an atomic mass of 133.

The name given to the alkane containing seven carbon atoms is heptane.
Cyclodecane is a ring of ten carbon atoms.
The IUPAC name for 9 is non. Therefore, it is known as nonane which means alkane with 9 carbon atoms.
Although carbon usually forms 4 chemical bonds, it's possible (though rare) for 5 bonds to form. The carbonium ion and superacid methanium (CH5+) is a gas that can be produced under low-temperature laboratory conditions.
At this moment, your body has a certain percentage of carbon-14 atoms in it, and all living plants and animals have the same percentage.
There is no 4 bond formed between carbon because of the carbon electron orbitals. Since it has 4 valence electrons, it needs 4 more to electrons to fill its outer energy level. It does so by forming covalent bonds with another element, in order to complete its Octet rule.

For example, hydrogen has an atomic number of 1. This means that an atom of hydrogen has one proton, and, if it's neutral, one electron as well.
Why can't oxygen have 9 protons?
Explain why it cannot have 9 protons. An oxygen atom has 8 protons in its nucleus, therefore, it's atomic number is 8. The element with 9 protons is , and thus it can't be oxygen.
On the periodic table of elements, magnesium is represented by the symbol Mg. It has an atomic number of 12 because it has 12 protons in its nucleus.
For example, a fluorine atom has 9 protons and 10 neutrons. Its atomic number is 9, while its atomic mass is 19 atomic mass units.
Hafnium is a divine element! Its most abundant isotope, 180Hf contains 72 protons and 108 neutrons (72 = 23 32; 108 = 22 33).
Platinum is a chemical element with the symbol Pt and atomic number 78.
Untriseptium (pron.: /uːntraɪˈsɛptiəm/), Uts, is the temporary name for element 137.
Rhenium is element 75 in the periodic table and in many ways a rather unusual element. It is one of the rarest elements on the Earth with an abundance of something like 1 part per million.
Magnesium has an atomic number of 12 and a mass number of 24. So a magnesium atom has 12 protons, 12 electrons, and 12 neutrons.
Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
The carbon atom (14C) nucleus on the top has 6 protons plus 8 neutrons. It has an atomic mass of 14.
How many electrons are in a carbon atom?
An isotope of chlorine has 21 neutrons.
4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.

For example, a fluorine atom has 9 protons and 10 neutrons. Its atomic number is 9, while its atomic mass is 19 atomic mass units.
Technically, any nucleus with 11 protons is sodium. The periodic table, after all, organizes the elements by the number of protons in their nuclei, and sodium is element number 11.
A: Carbon needs four more valence electrons, or a total of eight valence electrons, to fill its outer energy level. A full outer energy level is the most stable arrangement of electrons.
Carbon atoms comprise a nucleus of neutrons and six protons surrounded by six electrons. Quantum mechanics dictates that the first two electrons occupy the inner atomic orbital, while the remaining four electrons have wavefunctions that only half-fill the second standard and three second principal orbitals.
Carbon has 4 valence electrons and hydrogen has 1 electron. To complete its octet, carbon requires 4 electrons and hydrogen requires only 1 electron. So, the central carbon atom bonds with 4 hydrogen atoms so that both compounds can achieve their complete octet state.
