Question

Explain why the given electron configurations are not possible.

1.)[tex]1s^{2}2s^{1} 2p^{4}
2.)[tex]1s^{2}2p^{6} 3s^{2}3p^{6}
3.) $1s^{2} 2s^{2}2p^{5} 3s^{2} 3p^{5}$

Answer 1

Answer:

1) doesn't follow hund's rule

2) doesn't follow aufbau principle

3) p orbital occupies 6 electrons. only 5 is here. so, hund's rule is deviated
