Answer 2

(B) 11,11,12

Given - Mass number of atom = 23

Atomic number of atom = 11

As, no. of electrons in an atom is equal to an atomic number of the element.

So, number of electrons = 11

Secondly , number of protons are equal to number of electrons.

so, number of protons = 11

And number of neutrons = mass number - atomic number = 23−11 = 12

so, number of neutrons = 12

So , the atom contains 11 protons,
