Answer 2

Periodic Table

Explanation:

The image is missing in the question to show the options. Please find the attached picture for the image. The answer is with respect to the attached picture only.

(a) Most reactive metal is Z because size of atom increases down a group, resulting in decreased attraction of nucleus on valence electrons. The tendency to lose electrons increases, thus increasing reactivity.

(b) We know that electronegativity of non-metals increases from left to right in a period due to the increment of effective nuclear charge and decreases down a group due to the increment of size of atom. So, the most reactive non-metal is L.

(c) L, Q, R, T are the elements of the halogen family.

(d) Group 2 - Magnesium (Mg)

Group 13- Boron (B)

Group 15- Nitrogen (N)
