ASAP How many valence electrons does Lithium (Li) have? How do you know?

Lithium has a single electron in the second principal energy level and so we say that lithium has one valence electron.

Lithium has 1 valence electron

Explanation:

Valence electron are on the outermost shell, and if you look at lithiums model you will see 1 electron on the outer most shell

Hope this helps:)

the answer is true.
