No.of electrons in an atom is equal to atomic number of the element .
So no.of electrons in sodium is 11.
Secondly, no.of neutrons = mass number - no.of protons.
As protons are equal to electrons so 23 -11 = 12.
So sodium contains 12 neutrons 11 protons and 11 electrons

The element is SODIUM.
I have only written it for your understanding.
The arrangement of electrons in the shell is :- 2,8,1
No. Of protons- 11
No.of electrons - 11
No. Of neutrons - 12.
