Answer:
(D) chlorine has a greater ionization energy than sodium
Explanation:
Sodium is the element of the group 1 and period 3 which means that the valence electronic configuration is .
Chlorine is the element of the group 17 and period 3 which means that the valence electronic configuration is .
Ionization energy is the minimum amount of energy which is required to knock out the loosely bound valence electron from the isolated gaseous atom.
<u>Thus, removal of one electron in sodium is easy as it will gain noble gas configuration and become stable. But this case does not exist in chlorine and hence, chlorine has a greater ionization energy than sodium.</u>
So,
Sodium is much more apt to exist as a cation than chlorine because chlorine has a greater ionization energy than sodium.
