Because all alkali meals have same no of electrons (only one) in their outermost shell
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.
True. Lithium is unique among the alkali metals in terms of its physical and chemical properties. It is the lightest metal and has the highest melting and boiling points among the alkali metals. Additionally, lithium forms covalent bonds more readily compared to other alkali metals.

Why. Alkali. Metals are kept. In kerosene
Yes, chemical similarities exist between hydrogen and alkali metals; also the electron configuration has a parallel.
Alkali metals are all of the elements on the far left hand side of the Periodic Table with the exception of hydrogen. They are all highly reactive metals that also react vigorously with water.

Elements with an intermediate number of valence electrons will behave more like metals if they are on the left side of the periodic table, closer to the alkali metals. These elements tend to have low ionization energies and are more likely to lose electrons to form positive ions, exhibiting metallic characteristics such as conductivity and malleability.
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.
They don't
Alkali earth metals are named after their oxides, alkaline earth.
