They are very reactive
Alkali metals, such as sodium and potassium, are highly reactive and tend to combine quickly with other elements in nature to form compounds. This is because they have only one valence electron, which they easily lose to achieve a stable electron configuration. Therefore, it is rare to find pure alkali metals in their elemental form in nature.
The atomic radii of members of the Group 1A (Alkali metals), increases down the group. Therefore Francium has the largest atomic radius of the Alkali metals. However Fr has no stable isotopes, thus is not naturally occurring. So Cs-133 is the largest you can find.
The group on the very left of the periodic table.
because they are so reactive ,, we can find it in earth crust
The elements at the far left of the periodic table are called the "alkali metals," which are soft enough to be cut with a knife and reactive enough you'll never find them in nature as pure elements, only as salts.
Highly reactive
They are highly reactive.
In the first group of modern periodic table,i.e from hydrogen to francium.

The alkali metals, found in group 1 transition metals in groups 3 through 12
alkali is made out of a metal called zhphonie it is a very strong metal and is a substance to the earth

Alkali is a group of elements, not just one specific elements. Alkali metals are Group 1A elements starting with Hydrogen then lithium and so on.
The group on the very left of the periodic table.
Not only unlikely, but impossible. Potassium is a very reactive alkali element and react quickly to form compounds.
