Why is group one on the periodic table called the alkai metals?

Answer 1

Litmus paper changes color in acidic (red) and basic (blue) solutions. Given that "alkaline" is a synonym for basic, the title for Group IIA metals would literally be The Basic Earth Metals. Furthermore, "earth" is used because of the elements natural occurrence in the planet. It can also be determined from a lab that after Calcium (Ca) turnings are placed into distilled water, litmus paper will turn blue signifying the previously acidic solution has become more basic; many metals in Group IIA are the same.

Answer 2

Group II are alkaline earth metals. They are named alkaline because of the oxidation compounds that form basic alkaline solutions. They are named earth because they have extremely high melting temperatures, so they remain earth when placed in fire.

Answer 3

Group 1 elements are called alkali metals because they readily form alkaline solutions when they react with water, hence the name "alkali." These metals have one electron in their outermost shell, making them highly reactive and eager to lose that electron to achieve a stable electronic configuration.

Answer 4

in genral term alkali means base hence these all element react with water and produce strong alkyl hydroxide & these behaviour increases down the group

Answer 5

Group 1 elements dissolve in water to form alkali (or bases). Hence they are called alkali metals.

Answer 6

It is in the s block. they are highly reactive.

Answer 7

Because they react with water to form hydroxides which, in solution, are called alkalis.
