Question

Electron affinity of noble gases is

• A. Almost zero
• B. Low
• C. High
• D. Very high

Answer 1

Answer:

A. Almost zero

Read Explanation:

• Octet rule states that an atom can have the highest 8 electrons in its shell. If there are eight electrons or if an atom completes its octet, it becomes stable.

• Noble gases have a stable electronic configuration as their octet is complete. Therefore, they cannot accept more electrons.

• Electron affinity is the energy released when an isolated atom gains an electron.

• Since noble gases cannot accept electrons, their electron affinity is almost zero.
