Question

Neon atom requires energy to remove one electron from its outermost orbit, so also to add one electron into the outermost orbit. Which of the following is correct about fluorine? I. Fluorine releases energy when an electron is removed.
II. Fluorine requires energy to add one electron.

• A. (i) and (ii) are correct
• B. (i) is correct, (ii) is false
• C. (i) is false, (ii) is correct
• D. (i) and (ii) are false

Hint:

Halogens have high electron affinity → energy released on gaining electron.

Answer 1

The Correct Option is D

Concept: Ionisation energy and electron affinity govern electron removal/addition.

Step 1: Statement I.
Removing electron from fluorine requires energy → false.

Step 2: Statement II.
Fluorine releases energy when gaining electron → false.

Step 3: Conclusion.
Both statements are false.
