# How do you write the noble-gas electron configuration for helium?

Jan 8, 2018

Just as simple as $\left[H e\right]$!

#### Explanation:

Helium's electron configuration is $\left[1 {s}^{2}\right]$.

But, helium is in the last row of the periodic table, which are noble gases.

So, helium's noble gas configuration will be

$\left[H e\right]$.
