plz answer fast I will mark as brainlist answer​

Answer 1

Answer:

Explanation:No. Of protons & neutrons will be same i.e 8& 8 but the no. Of electron will be (8+2)(because it gains two electrons to form O2-ions)=10 electrons

Answer 2

Explanation:

Protons 8 as there is no gain or loss of protons hence it is same as atomic number

Electrons 10 as it has gained two electrons

Neutrons 8 as neutrons are mass number- atomic number i.e 16 - 8 = 8
