Question

A Group VIIA atom combines with a Group IA atom. The bond formed between them will most likely be:

Answer 1

Answer: The correct answer is option B.

Explanation:

• Ionic bond is formed when there is complete transfer of electrons from one element to another.

• Covalent bond is formed by the sharing of electrons between two elements.

• Metallic bond is formed when two metals combine together.

Electronic Configuration of Group VII-A : $ns^2np^5$

This group require 1 electron to attain stable electronic configuration.

Electronic configuration of Group I-A : $ns^1$

This group will loose 1 electron to attain stable electronic configuration.

So, there will be complete transfer of electron from Group VII-A to Group I-A and hence, will form ionic bond between them.

Hence, the correct option is B.
