Because Hydrogen is a gas that has metal in the element
Hydrogen is grouped with alkali metals because it has similar chemical properties, such as having one electron in its outer shell and being reactive. However, hydrogen is not a true alkali metal as it does not readily form a cation with a 1+ charge like the alkali metals do.
Alkali metals can be substituted for hydrogen. Any of them. They include lithim (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr). The alkali metals are in group one of the periodic table of the elements, and are all stacked up in the column below hydrogen. All the alkali metals are all organized with a lone electron in their outer most shell, or valence shell (in the neutral atom) and all of the alkali metals would like to loan out that electron to anything that would like to borrow it. It turns out that the reactivity of alkali metals are least to greatest from the top of the column to the bottom. This is because of electron screening.

No, hydrogen is a nonmetal. It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do. Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.
Hydrogen shares some properties with alkali metals, particularly in its ability to lose one electron to form a cation with a +1 charge like alkali metals. However, hydrogen is a nonmetal and not a metal like the alkali metals.
As with all alkali metals, hydrogen has one electron in its outermost shell.

The electron configuration of hydrogen is similar with that of alkali metals.
As with all alkali metals, hydrogen has one electron in its outermost shell.
Hydrogen is a non-metal; it's in group VII
(A similar relationship exists in Group 1, which includes hydrogen and the alkali metals. All have the same valence configuration, but hydrogen is never included as a member of the alkali metals family.)
It is much more common for hydrogen to lose an electron and become H+ than it is for it to become H- (like a halogen would), as in a hydride. Because it is possible for either behavior, though, some periodic tables DO show hydrogen in group 17. Some show it in group 1. Some show both, and some show hydrogen sitting in the middle by itself. It's a tricky one.

For example hydrogen is released when alkali metals react with water.
the elements on the far far right are called alkali metals (Group 1) and alkali earth metals (group 2)
