Solution
Cations:
A cation is a positively charged ionic species.
"Cation" is derived from the Greek word "Kato," which means "down."
When a metal's electrons are stripped away, they form.

A cation has a net positive charge because the protons outnumber the electrons.
Multiple-charged cations may be given unique names.
