The first ionisation potential in electron volts of nitrogen and oxyge – InterviewSolution

InterviewSolution

1.	The first ionisation potential in electron volts of nitrogen and oxygen atoms are respectively given byA. 14.6,13.6B. 13.6,14.6C. 13.6,13.6D. 14.6,14.6
Answer» Correct Answer - A First ionisation potential of nitrogen is more than oxygen. It is due to exactly half filled p-subshell in N.Thus ionisation potentials (in eV) of N , O are 14.6, 13.6 respectively.
