Question:
Electron affinity of noble gases is
AAlmost zero
BLow
CHigh
DVery high
Answer:
A. Almost zero
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.
