Question

Which electronic configuration is not possible?
1) 2p
3) 35'
4) 45​

Answer 1

Explanation:

The required "option (2) 2d^5 "is not possible.

Explanation:

The electronics configuration are possible:

1s^2

2s^2 2p^6

3s^2 3p^6 3d^{10}

4s^2 4p^6 4d^{10} 5f^{14}

5s^2 5p^6 5d^{10} 5f^{14}

The electronics configuration 2d^5 is not possible because 2s^2 2p^6 is possible only.

Thus, the required "option (2) 2d^5 "is not possible.

Answer 2

Answer:

+ = 1, = 30° and B is an acute angle, then find the value of B
