Electron affinity of :

Electron affinity is the

The electron affinity of

Electron affinity is the :

Give reasons why? Noble gases have Zero electron affinity.

In comparison with alkali metals, the electron affinity of halogens is

Which of the following elements has zero electron affinity ?

The element having very high ionization enthalpy but zero electron affinity is :-

The element having very high ionization enthalpy but zero electron affinity is:

Metals have few electrons in their valence shell while non-metals generally have more electrons in their valence shell. Metallic character is closely related to atomic radius and ionisation enthalpy. Metallic character increases from top to bottom in a group and decreases from let to right in a period of periodic table. metallic character is inversely related to electronegativity of element. Q. 3 N_0//2 atoms of X_((g)) are converted it into X_((g))^(+) by energy E_(1) , 2 N_0//3 atoms of X_((g)) are converted it into X_((g))^(-) by energy E_(2) . hence, ionisation potential and electron affinity of X_((g)) are: ( N_(0) =Avogadro's number)
