Question

Atomic number of three elements a b and c are a a+1 a+2 is an alkali metal. In the compound of a and c the nature of bonding is



a.Coordinate b)covalent



c.Ionic



d.Metallic

Answer 1

Ionic because 1 group elements have 1 e- in there outermost shell and usually form ionic bonds

Answer 2

Answer:

The nature of bonding is an option (c) Ionic.

Explanation:

• C has the atomic number a+2 and is an alkali metal. As a result, B must be an inert gas with the atomic number a+1.
• Because proceeding right on the periodic table from the alkali metals family, i.e. from the s-block elements, we arrive at the inert gas family series, which is the 18th group.
• Because it occurs before the inert gas group, element A with the atomic number must be a member of the halogen group.
• Because halogens are non-metals, they will form ionic bonds with alkali metals.

So, option (c) Ionic is the right answer.
