How can the atomic number be determined?
The number of protons present in the atom is knowns as atomic number. It can also be defined as the number of electrons present in a neutral atom. Each elements has it's own At. no. .
Mathematically, atomic number = no. of protons = no. of electrons
or, Atomic number = number of
For example, in one hydrogen atom, number of
In one carbon atom, number of
Hence we can conclude that the Number of protons or electrons present in the atom, determines the Atomic number .
