They're different elements sis....
Elements can be same only if number of protons on each atoms are same.
Here, the element having 11 protons and 12 neutrons is Sodium atom(Na): Atomic number:11 Mass number:11+12=23
And the element having 12 Protons and 12 neutrons is Magnesium atom(Mg):
Atomic number:12 Mass number: 12+12=24 ..(Average atomic mass of Magnesium is 24.3 because of isotopes)
If still u've doubt, u can comment below.
