Question

if hund's rule is not available guess and write the changes in electronic configuration of nitrogen​

Answer 1

Answer:

In writing the electron configuration for nitrogen the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for N goes in the 2s orbital. The remaining three electrons will go in the 2p orbital. Therefore the N electron configuration will be 1s22s22p3.

Explanation:

Answer 2

Answer:

total unpaired electrons if Hund's rule is not followed is 1. Hence only one electron will be unpaired if this rule is not followed or is not applicable in a NO molecule. Out of total 15 electrons of both nitrogen and oxygen 14 will get paired and one will remain unpaired.
