Nitrogen has three unpaired electrons in outermost shells according to
Correct answer: C. Hund's rule
- A. Aufbau principle
- B. Pauli's exclusion principle
- C. Hund's rule
- D. Le chatilier principal
Explanation
Correct option is C Thus, nitrogen contains three unpaired electrons following Hund's rule of maximum multiplic According to this rule, electron pairing in any orbital (s, p, d or f) does not take place until each orbital of the a subshell contains one electron with paralell spin.The electronic configuration of nitrogen is 1s2 2s2 2p3.Nitrogen is Trivalent.FTB Pg42

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
