The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
The hydrogen atom has 1 electron.
An atom with single electron in its outermost shell
Negative
negative
This atom become a cation (positive).
no

The simplest atom that has one electron and one proton is the Hydrogen atom.
Covalent bond
electron
An ionic bond.
These are the electrons from the outer shell of an atom.
