Question

group1 A metals are called alkali metals,why?

Answer 1

They are placed in the vertical column on the left-hand side of the periodic table . All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.

Answer 2

because they form alkalies( i.e. strong bases capable of neutralizing acids) when they react with water.
