 X_{8}^{16} depicts that its atomic no. is 8 And mass no. is 16

No. of neutrons = mass no. - atomic no. = 16 - 8 = 8
No. of electron = no. of proton = atomic number = 8

Hope it helps...

Atomic Number = 8

Atomic mass = 16

No of electrons = no of protons = atomic number=
8 = 8 = 8

Mass number = 16

No of neutron = Mass number - Atomic number
=16-8=8
