Group 1, which are the Alkali Metals.
Only one valence electron.
There is only one valance electron in potassium.
Every sodium atom has only one valence electron.
Hydrogen (H) only has one electron. If you are talking about valence electrons, all of the elements in group 1A on the periodic table have one valence electron (H, Li, Na, K, Rb, Cs and Fr).
Rubidium has one valence electron in the 5th energy level, while strontium has two valence electrons in the 5th energy level. Since rubidium has only one valence electron compared to strontium's two, the valence electron in rubidium is further from the nucleus. This is due to the increasing number of electron shells as you move down a group in the periodic table.
One. A hydrogen atom contains only one electron, and it is a valence electron.

One.Hydrogen has only 1 electron in total, and it is also a valence electron.
Hydrogen has only one electron. Just the one. And it is a valence electron.
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
Only one valence electron.
Platinum only has one valence electron
The elements with only one valence electron are a part of the Alkali Metals: * Lithium * Sodium * Potassium * Rubidium * Cesium * Francium Hydrogen also only has one valence electron, but it is not considered part of the Alkali Metals family, nor any other family.
There is only one valance electron in potassium.
there is one valence electron in hydrogen, and it needs one more electron to become stable
Hydrogen doesn't really have a valence shell. It has one electron only.
Francium has one valence electron, its atomic no is 87 and it belong to Ist group of periodic table.
