Answer:
Symbol : 11 - Sodium (Na)
ATOMIC NO. -11
NO. OF ELECTRONS - 11
MASS NO. - 23
NO. OF PROTONS = NO. OF ELECTRONS
THEREFORE NO. OF p+ = 11
No. of neutrons = Mass no. - No. of protons
= 23-11
= 12
12 - Magnesium (Mg)
Atomic no. - 12
No. Of Electrons - 12
No of protons - 12
No. of neutrons - 12
Mass no. - 24.
Hope it helps
