Question

Why is the electron affinity of neon greater than any other noble gases

Answer 1

The Question is little ambiguous..

But still I m trying to answer up to ur satisfaction..

Explanation:The size (atomic radius) of Neon is bigger..because the outer shell of neon is complete (octet). As a result, the effect of nuclear pull over the valence shell electrons cannot be seen. Hence the electron affinity of neon is greater...

I hope u understood..

Answer 2

Answer:

As you move down a group on the periodic table, electron affinity decreases.

Explanation:

Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion

For example, the electron affinity of chlorine has the negative sign, which shows us the energy that is released to add one electron to an atom.

FACTOR AFFECTING ELECTRON AFFINITY

• Atomic size
• Nuclear charge
