Group 1: the group on the far left of the Periodic Table.
All the atoms in group 1.
The elements in wide form periodic table column 1.
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).
In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium. The farther you move right on the periodic table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
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.
Atoms with 1 valence electron are typically found in Group 1 of the periodic table, known as the alkali metals. Examples include lithium, sodium, and potassium, all of which have one valence electron in their outermost energy level. This lone valence electron makes these elements highly reactive.
One. A hydrogen atom contains only one electron, and it is a valence electron.

Almost all elements have multiple valence electrons, there are only 7 that don't. They are: hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium. The elements have 1 valence electron. All other elements have anywhere from 2 to 8 valence electrons
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
Hydrogen has only one electron. Just the one. And it is a valence electron.
