hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.
Alkali Metals
they all have one valence electron.
Valence electrons are located in the outermost shell in an atom. Chromium has only one valence electron.
these atoms offer the least amount of resistance for knocking the valence electron out of its orbit.
Every sodium atom has only one valence electron.

A valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.) It is an electron in the outermost shell of the atom.
One. A hydrogen atom contains only one electron, and it is a valence electron.
when it is on the very outside level away from the nucleusA valence electron is one that occupies the highest energy level for any electron in a particular neutral atom. (There may be more than one such electron in a single atom.)It is an electron in the outermost shell of the atom.
A sodium atom has one valence electron.

One valence electron
Just one valence electron. The electron configuration for K-42 is 2-8-8-1, meaning that there is one electron in the outermost "shell" of the atom.
If one electron is gained, then it has a charge of -1.
The outermost electrons are called VALENCE electrons.
