Question

35.

O2- is smaller than S2-.

Atomic number of O = 8
Atomic number of S = 16
In case of sulfur an extra shell is added.

Na+ is smaller than Na

Na+ has 1 electron less than Na but both have same number of protrons.

Al3+ is smaller than Mg2+

Both have 10 electrons but Al has 13 protrons whereas Mg has 12 electrons.

Cl is smaller than Cl-

Cl- has an extra electron where as both have same number of protrons.

Au3+ is smaller than Au+

Au3+ has two electrons less than Au+, but both have same number of protrons.
