Give a phrase for : Amount of energy released when an atom in the gaseous state accepts an electron to form an anion.

Arrange the following:

(i) N, Be, O, C (in increasing order of non-metallic character)

(ii) P. Si, F. Be (in decreasing order of valence electrons)

In the 2nd period Neon has maximum Ionization Potential because:

1. It has unstable electronic configuration.
2. It easily accepts electrons.
3. It easily loses electrons.
4. The outer most shell is completely filled.

Electron Affinity is maximum in:

1. Mg
2. Ar
3. Li
4. Br
