(a)
Interpretation:
Determine the electron configuration of atoms using the appropriate noble gas configuration of the core electrons.
Concept Introduction:
Electron configuration describes the positions of electrons of an atom. These positions were explained by several models developed by different scientists. Principal energy level, Type (shape) of orbital and No: of electrons in the orbital are respectively represented by an atom’s electron configuration.
