hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.
they all have one valence electron.
Valence electrons are those in the outermost shell of the atom.
Valence electrons are located in the outermost shell in an atom. Chromium has only one valence electron.
Every sodium atom has only one valence electron.
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)

This atom lose an 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.
Each potassium atom has one valence electron available for bonding.
One. A hydrogen atom contains only one electron, and it is a valence electron.
A hydrogen atom has 1 valence electron.
they all have one valence electron.
There is one valence electron in a neutral sodium atom. Sodium has an electron configuration of 2-8-1, indicating it has one electron in its outermost energy level.
A sodium atom has one 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.
The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.
Valence electrons are those in the outermost shell of the atom.
