It has a negative charge.
If there is an extra electron in the valence level then the electron is in the excited state and is carrying more energy. If the atom is normal then it is in the ground stte and contains low energy.
The atoms sharing the electron pairs will spread out around the central atom.
The atoms sharing the electron pairs will spread out around the central atom.
The atoms sharing the electron pairs will spread out around the central atom.
An atom with one extra electron is called an anion, while an atom with one missing electron is called a cation.
The atoms sharing the electron pairs will spread out around the central atom.

If a fluorine atom were to attract an extra electron from a lithium atom, the lithium atom would become a positive charge because it loses an electron.
Anion.
The atoms sharing the electron pairs will spread out around the central atom. Apex
