Consider the electronic configuration for atoms (X) `1s^(2) 2s^(2) 2p^(6) 3s^(1) " " (Y) 1s^(2) 2s^(2) 2p^(6) 4s^(1)`
Which of the following statement (s) us (are) NOT true?

A

Energy is required to change (X) to (Y)

B

(X) represents Na atom

C

(X) and (Y) represents different elements

D

More energy is required to remove one electron from (Y) than from (X).

Text Solution

Verified by Experts

The correct Answer is:
C, D
X and Y represent same element i.e., `Na (Z =11)` and less energy is required to remove an electron from (Y) than atom (X)
