The proton identification identification chassis of an element is defined as the result of protons in its kernel. Proton fall is represented by the figure Z. ? In a achromatic atom, the proton consequence also represents the number of electrons in orbit. ? The protons and neutrons in the nucleus of an atom are called nucleons. ? The nucleon number of an atom is defined as the total number of protons and neutrons in its nucleus.

Nucleon number is represented by the symbol A. ? Number of neutrons N in the nucleus :- N = A - Z Nuclide Notation ? The nucleus of an atom with a particular number of protons and neutrons is called a nuclide. A nuclide is reffered to by its nucleon number, for example, atomic number 3 6 and carbon 12. ? all(prenominal) type of tom has a symbol. For example, H is the symbol for henry atom. ? If an atom of an element X has a nucleon number A and a proton number Z, its nuclide is repersented by the following notation : Isotopes ? Isotopes of an element are atoms which have the family number of...If you want to lounge around a full essay, chump it on our website: Ordercustompaper.com
