Which group of metals includes elements with one valence electron?

Answer 1

The group of metals that includes elements with one valence electron is known as the alkali metals. This group is located in Group 1 of the periodic table and includes elements such as lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). These metals are highly reactive and tend to readily lose their single valence electron to form positive ions (cations).
