please explain it too​

Answer 1

Answer:

ns1 ------- 14,200,220,240

ns2 ------- 18,26,230,240

ns2 np1 --- 16,28,34,260

ns2 np2 ---- 19,27,36,48,270

Explanation:

Check the number of ionisation energies after which there is a sudden increase in the ionisation energy and based on that in the first one that is ns1 after one electron there is a sudden rise in ionisation energy which means there is only one electron in the valence shell samd goes for rest three
