It is convenient to describe the composition of an atom in terms of the number of protons and neutrons in its nucleus (Figure 1 ). The term atomic number , conventionally denoted by the symbol Z , indicates number of protons present in the nucleus of an atom, which is also equal to ...
Atomic Number vs Mass Number Atoms are characterized by their atomic numbers and mass numbers. In the periodic table, atoms are arranged according to the
