# What is the electron configuration of Li+?

Mar 18, 2018

The parent lithium atom has $Z = 3$..

#### Explanation:

And if there are 3 positive nuclear charges, the ATOM must contain 3 negative, extranuclear charges, 3 electrons, that are conceived to whizz about the massive nuclear core....

And using the standard $\text{aufbau scheme}$...we gots...

Z=3;1s^(2)2s^1....FOR NEUTRAL lithium

And should lithium be ionized...

$L i \left(g\right) + \Delta \rightarrow L i {\left(g\right)}^{+} + {e}^{-}$

...we gots ${\left\{1 {s}^{2}\right\}}^{+ 1}$

The lone valence electron places lithium at the head of the alkali metals....lithium, natrium, potassium....all of which are ionized facilely....
