Chapter 5, Problem 5.22P

(a)

Interpretation Introduction

Interpretation:

For the ground-state electronic configuration of silicon, noble-gas shorthand notation has to be written.

Concept Introduction:

Electrons of an atom are arranged in orbitals by the order of increasing energy.  This arrangement is known as electronic configuration of atom.  This can be represented using noble-gas shorthand notation also.

In the noble-gas shorthand notation of electronic configuration, the electrons that are in excess in comparison with the nearest noble gas is written.  The symbol of nearest noble-gas is written in square brackets followed by the excess electrons.
