Expert Answer
Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes.
Lets remember this notation : AXZ. Here X is the chemical symbol for the element, Z is the atomic number, and A is the number of neutrons and protons combined, called the mass number.
Hydrogen is written 1H1, deuterium is2H1, and tritium is 3H1. These are isotopes.
Please specify what other parameters you want to discuss about.
