# How many valence electrons does the element plutonium have?

May 10, 2018

$2$

#### Explanation:

Plutonium's electron configuration is a weird one, where it is:

$\left[R n\right] 5 {f}^{6} \setminus 7 {s}^{2}$

Its outermost shell is therefore its $7 s$ shell, which contains $2$ electrons, and therefore it has $2$ valence electrons.
