Question

Statement:1 - Isotopes have the same chemical properties.
Statement:2 - Isobars have different chemical properties.

• A. Both Statement:1 and Statement:2 are false
• B. Both Statement:1 and Statement:2 are true
• C. Only Statement:1 is true
• D. Only Statement:2 is true

Answer 1

The correct option is B

Both Statement:1 and Statement:2 are true

(a) As electronic configurations of different isotopes are the same, so they have the same chemical properties.
(b) Isobars have different electronic configurations and, hence, they have different chemical properties.
