Yes they are!
even though they are very soft, reactive and not as widely used as much as transition metals eg. in construction they still have other metallic properties, such as metallic bonding.
Alkali metals are very electropositive because they have only one electron in their outermost shell, which is easily lost to form a positive ion. This low ionization energy makes it easier for alkali metals to lose this electron and become positively charged, resulting in their high electropositivity.
The most electropositive element in Group IA (alkali metals) is cesium (Cs). Electronegativity decreases down the group, making cesium more willing to lose its outer electron compared to other alkali metals like lithium, sodium, and potassium. This characteristic makes cesium the most reactive and electropositive element in its group.
SHORT ANSWER: the difference in electronegativities between H and Alkali metals is high, so the bonds are more ionic.
Electropositive metals are metals that have a tendency to lose electrons and form cations in chemical reactions. These metals typically have low electronegativity and easily give away their outer electrons to achieve a more stable electron configuration. Examples of electropositive metals include alkali metals like sodium and alkaline earth metals like magnesium.
Alkali metals typically bond with elements from Group 17, known as the halogens. This is because alkali metals have one electron to donate, while halogens have one electron missing to complete their outer electron shell, creating an opportunity for a strong ionic bond to form between the two groups.

Metals that lose electrons easily are called "reactive metals" or "electropositive metals." These metals have low ionization energies, which allow them to readily give up electrons to form positive ions.
Alkali metals are the most reactive metals.

Alkali metals are very reactive metals.
No, alkali metals are not the only earth metals. Earth metals include both alkali metals and alkaline earth metals. Alkaline earth metals are a group of elements in the periodic table that are chemically similar to, but less reactive than, alkali metals. Examples of alkaline earth metals include magnesium, calcium, and barium.
An electropositive element is one with very low electronegativity. These are typically the metals (alkali metals, alkaline earths, etc.). In order to form a stable valence shell configuration, they most easily lose electrons.
They don't
Alkali earth metals are named after their oxides, alkaline earth.
