Question

Which of the following is hydrogen’s electronic configuration?

(a) 1s^1

(b) 1s^2

(c) 2s^1

(d) 2s^2

I had been asked this question in an internship interview.

I want to ask this question from Position of Hydrogen in the Periodic Table in chapter Hydrogen of Chemistry – Class 11

Answer 1

The correct answer is (a) 1s^1

For explanation: The electronic configuration of hydrogen is 1s^1, as it has only one Proton. It belongs to the first group and is ready to gain one electron in order to become a noble gas like helium which is next to it.
