Question

Statement I: ${}^{20}Ne$ and ${}^{22}Ne$ are isotopes.
Statement II: Noble gases do not exist as isotopes as they are inert.

• A. Both statements are true
• B. Both statements are false
• C. Only Statement I is true
• D. Only Statement II is false

Answer 1

The correct option is C

Only Statement I is true

Neon ${(}_{10}Ne)$ possesses three stable isotopes, ${}^{20}Ne{,}^{21}Ne$, and ${}^{22}Ne$.

Neon is a noble gas and exists as three different isotopes, therefore, the first statement is true but the second one is false.
