dually ionised Silicon (S -2)
No of protons = Atomic number(Silicon = 16)
No of electrons = Atomic number (16) + 2 electrons (anion) = 18
No of neutrons= Mass number - Atomic Number = 32-16= 16
No of protons = Atomic number(Silicon = 16)
No of electrons = Atomic number (16) + 2 electrons (anion) = 18
No of neutrons= Mass number - Atomic Number = 32-16= 16
