Answer 1

S2- is greater than Cl-  and C4- is larger in size than F-

Explanation:

• (a) S2- is greater than Cl-
• (b) C4- is larger in size than F-

The atomic number of Sulfur is 16 and its electronic configuration is

1s^2, 2s^2, 2p^6, 3s^2, 3p^6 (It has gained two more e-)

The atomic number of Cl- is 17

It's electronic configuration is 1s^2, 2s^2, 2p^6, 3s^2,3p^6

The atomic number of C is 6.

It's electronic configuration is 1s^2, 2s^2, 2p^6

The atomic number of F is 9

It's electronic configuration is 1s^2, 2s^2, 2p^6
