Atomic number = No. of electrons = No.of protons
so, the number of electrons is 11
the number of neutrons = 23 - 11 = 12

Protons = electrons, so there are 11 of both.
Subtract 11 from 23 to get the neutrons.

The atomic number is equal to the number of protons.
In an element no. protons = No electrons.

Mass = No protons + No neutrons.
