Answer:
Atomic Number- 16
Mass Number- 32
Explanation:
According to question ion is X2- , which means it has gained 2 electrons, which means in its neutral states it had 16 electron, since it's neutral atom it had 16 protons too( to maintain neutrality), thus atomic number is 16 , now
16 protons + 16nuetrons = 32 nucleons
Therefore mass number is 32
