Nitrogen atom is represented at ^147N. How many electrons does it need to attain the noble gas configuration?(a) 1(b) 2(c) 3(d) 4I had been asked this question in exam.I'd like to ask this question from P-Block Elements topic in chapter P-Block Elements of Chemistry – Class 12

Answer»

Correct answer is (c) 3

For explanation I would say: With five ELECTRONS in its outer most shell, it needs three more electrons to have a complete shell CONSISTING of eight electrons which is the noble electronic configuration. The ion formed by the nitrogen atom is N^3-. It ATTAINS the electronic configuration on neon.
