Question

What is the electron configuration of Li+?

Answer 1

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 `"aufbau scheme"`...we gots...

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

And should lithium be ionized...

`Li(g) + Delta rarr Li(g)^++e^(-)`

...we gots `{1s^(2)}^(+1)`

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