Answer:

Option a

Explanation:

a) I^-

Atomic number of I = 53

No. of electrons = atomic number + no. of negative charge

                           = 53 + 1 = 54

Xe

Atomic number of Xe = 54

In a neutral atom, no. of electron is equal to no. of protons.

So. no. of electron in Xe = 54

a) Ba^{2+}

Atomic number of I = 56

No. of electrons = atomic number - no. of positive charge

                           = 56 - 2 = 54

All the species in the set a have 54 electrons.
