Question

Assertion :An element (X) with an atomic number of 16 has 14 electrons in $X^{2-}$ Reason: Two protons bind the two outermost electrons

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is D Both Assertion and Reason are incorrect

$X^{2-}$ means it gained $2e^{-}$

$\therefore$ No. of $e^{-}=16+2$

$=18$

$\therefore$ Assertion is incorrect

No. of protons bind the outermost extra $e^{-}$

$\therefore$ Reason is incorrect too
