Respuesta :
Alkali metals are all highly reactive (D is false) so they would not be found in their uncombined form (A is true) ans at least some of them are highly water soluble ( C is false) (b is false) Check out the Periodic Table - you will see the Alkali metals.
The statement that is true about alkali metals is some of them explode when exposed to water.
What is alkali metals?
The alkali metals refer to a group in the periodic table comprising the chemical elements like sodium, lithium, rubidium, potassium, francium, and cesium. Together with hydrogen they constitute group 1, which lies in the s-block of the periodic table.
The alkali metals have the high thermal and electrical conductivity, luster, ductility, and malleability that are characteristic of metals. Every alkali metal atom has one electron in its outermost shell.
Due to single electron in outer most shell they are highly reactive. Some of them even explode with cold water, leading to the displacement of hydrogen.
