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.

Answer: When sand is added to water it either hangs in the water or forms a layer at the bottom of the container. Sand therefore does not dissolve in water and is insoluble. It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation.
