Find the correct statement about electron affinity (E.A).

: For an element,$\mathrm{E}.{\mathrm{A}}_2$ is always positive (due to avoid the electron repulsion forces between the anion and incoming electron).
Note: In a period from left to right E.A value increases gradually.
For ‘p block elements’ 3rd period elements have more E.A values than 2^nd period elements within in a same group.
