Z=8, number of neutrons=9 All the protons are present in the nucleus, or centre of an atom. A protonis one of thesubatomic particlesthat make up matter. Nevertheless, it was not entirely accurate, because contrary to what Dalton believed, atoms can, in fact, be broken apart into smaller subunits or subatomic particles. These forms of carbon are found in the atmosphere in relatively constant proportions, with carbon-12 as the major form at about 99%, carbon-13 as a minor form at about 1%, and carbon-14 present only in tiny amounts, After a half-life of approximately 5,730 years, half of the carbon-14 that was initially present will have been converted to nitrogen-14. They are a type of fundamental particle called leptons.

On the other hand, the masses of protons and neutrons are fairly similar, although technically, the mass of a neutron is slightly larger than the mass of a proton. " Most times I find this type of training long and boring; however this was not the case, it seemed as if time flew by. Cerium is an important component of mischmetal alloy.
