The best and most correct answer among the choices provided by the question is the fourth choice or letter D.
<span>A2+ would represent the ion of an element from Group 2A</span>
I hope my answers has come to your help. God bless and have a nice day ahead!
nitrogen (N), antimony (Sb), bismuth (BI)
Explanation:
Electrical conductance increases from Nitrogen to antimony and then Bismuth. Electrical conductance increases with available free electrons.
- The elements listed belongs to Group V on the periodic table.
- Group V elements are Nitrogen, Phosphorus, Arsenic, Antimony, Bismuth.
- As we go down the group, electrical conductance increases.
- This is because the radius of the atom becomes larger and the pull on the outer electrons become very weak.
- Outer electrons becomes free to facilitate electrical conductance.
- We can also see that metallicity i.e electropositivity increases down the group.

D because i did this last week and got it right.
Hi,
I think the answer is metric.
