Interpretation:
Number of valence electrons in
Concept Introduction:
The fundamental principles that are followed to write an electronic configuration include three rules as follows:
Electron in a
Hund’s rule suggests electrons are not allowed to be paired up until each degenerate set of orbital has got at least one electron.
Pauli Exclusion Principle states two electrons within the same orbital cannot possess same set for four possible quantum numbers.
In chemical reactions, only outer electrons are involved thus the electronic configuration is simplified when the core electrons are represented by the closest noble gases followed by valence electrons. For instance, nitrogen with
