Question

A highly ionic compound is formed by the combination of elements belonging to:

• A. I A group and VII A group
• B. II A group and VI A group
• C. III A group and V A group
• D. 0 group and VII A group

Answer 1

Answer: (A)

I A group and VII A group

A highly ionic compound is formed by the combination of elements belonging to I A group and VII A group because I A group elements lose electrons easily (most electro-positive) and VII A group elements gain electrons easily (electro-negative). So, the compound formed by these elements can easily be ionised.
