Assertion: Electron affinity value of the 3 textrd period element is more than 2 textnd period element. Reason: Due to smaller size of the 2nd period, its electron density increases which eases the addition of electron.

I.E. of 3 textrd period is more than II this is due to the high electron density of 2 textnd period element which makes it difficult the addition of electron in its outermost shell.

Q. Assertion : Electron affinity value of the $3 rd$ period element is more than $2 nd$ period element.
Reason : Due to smaller size of the 2nd period, its electron density increases which eases the addition of electron.

Both A and R are true and R is the correct explanation of A.

Both A and R are true but R is not correct explanation of A.

A is true but R is false

Both A and R are false.
