Question

why are the members of group IA called alkali metals

Answer 1

Here is Ur answer,

Group 1A elements are called as alkali metals because those elements form alkalies(water soluble bases) when react with the water.

Answer 2

Answer:

The members of group IA called alkali metals

Explanation:

Alkali metals:

Alkali metals are any of the elements found in Group IA of the periodic table (the first column). Alkali metals are very reactive chemical species that readily lose their one valence electron to form ionic compounds with nonmetals. All elements in the alkali metal group occur in nature.

Why are the members of group IA called alkali metals.

The group 1 of the periodic table contain six elements namely Lithium(Li), Sodium(Na),Potassium(K),Rubidium(Rb),Cesium(Cs) and Francium(Fr). These metals are called alkali metals because they form alkalies ( i.e. strong bases capable of neutralizing acids) when they react with water.

These metals are soluble in water and form metallic hydroxides and evolve hydrogen gas. These hydroxide are called alkalies. Therefore the elements of group IA are called alkali metals.
