No. Of neutrons = Mass no. - Atomic no.

= 23 - 11 = 12

And just btw ur question is wrong. There cannot be 12 electrons as metals don't take electrons they only give and sodium is a metal


renubala8080gm57: brother in que i done a mistake . the electrons are not 12 it is 11. i think by using elec 11 you proton should be 11. please show me formula also. pleaseeeee
VedanshSomani: atomic no. = no. of protons = no. of electrons = 11
VedanshSomani: mass no. = atomic no. + no. of neutrons. or. mass no. = no. of protons + no. of neutrons
VedanshSomani: now, mass no. = 23
VedanshSomani: so, 23 = 11 + no. of neutrons
VedanshSomani: And, no. of neutrons = 23 - 11 = 12
VedanshSomani: hope u understand
