Alkali metals
Alkali metals, such as sodium and potassium, are characterized by having a single valence electron and very reactive atoms. They readily lose this outer electron to form +1 cations in chemical reactions.
Alkali group 1 metals have one valence electron, which makes them highly reactive. They have low melting and boiling points and are soft metals that can be easily cut with a knife. These metals also tend to form ionic compounds due to their tendency to lose their single valence electron.
The alkali metals (lithium, sodium, potassium, rubidium, caesium, and francium) all have a single valence electron and tend to be very reactive. Note that hydrogen also has a single valence electron and is very reactive but it does not become metallic except at very, very, very low temperatures.or very, very, very high pressures (at least theory predicts it would be).
Alkali metals such as Li, Na, K, Rb, Cs, and Fr each have 1 valence electron. This is because they have a single electron in their outermost electron shell, making them highly reactive and likely to lose that electron to achieve a stable electron configuration.
Alkali Earth metals have a single valence electron, and are found in the first group.
The alkali metals easily yield the one electron found in their valence shell, to bond with other elements. Since it takes so little energy to remove this electron from an alkali metal (i.e., they have a low ionization energy) these metals are never found in nature in their elemental forms (they are too reactive; i.e., their atoms so easily bond to other atoms).
Elements in Group 1 are the most reactive because they have a single electron in their outermost energy level, making them highly unstable and eager to lose that electron to achieve a full valence shell. These elements, such as lithium, sodium, and potassium, react vigorously with other substances to achieve a more stable electron configuration.
