# What is the noble gas notation for germanium?

Apr 30, 2014

Germanium (Ge) is located in the 4th energy level (row) of the periodic table, column 14 (IVA). This position would be an electron configuration of

$1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{10} 4 {p}^{2}$

To convert this to the Noble Gas notation we revert back to the Noble Gas from period 3 of the periodic table Argon

Argon - Ar $1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6}$

We then replace this section of Germanium's electron configuration with [Ar].

$\left[A r\right] 4 {s}^{2} 3 {d}^{10} 4 {p}^{2}$
