Question

how is the atomic number related to number of electrons and protons?

Answer 1

Atomic number is always equal to number of protons in an atom in its stable state and also equal to number of electrons.

For stable atom :-

No of protons=No of electrons=Atomic No.

But for ions or charged atoms the atomic number is equal to number of protons but not equal to number of electrons. Number of protons minus the charge is equal to number of electrons.

For ions :

No of protons =Atomic No.

i hope it helped u

Answer 2

The atomic number of a stable element is = total number of electrons =total number of protons
