Question

STATEMENT - 1: ${}^{20}Ne$ and ${}^{22}Ne$ are isotopes.
STATEMENT - 2: Noble gases do not exist as isotopes as they are inert.

• A. Statement 1 is true but Statement 2 is false
• B. Statement 1 is false but Statement 2 is true
• C. Both Statements are true
• D. Both Statements are false
