Question

what are alkali metals?​

Answer 1

Answer:

any of the elements lithium, sodium, potassium, rubidium, caesium, and francium, occupying Group IA (1) of the periodic table. They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.

Alkali metal, any of the six chemical elements that make up Group 1 (Ia) of the periodic table—namely, lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). The alkali metals are so called because reaction with water forms alkalies (i.e., strong bases capable of neutralizing acids).

Answer 2

The alkali metals are the group of elements that have one valence electron in their outermost energy level (group 1). They are found in nature bonded with other atoms because they are so reactive. The alkali metals are lithium, sodium, potassium, rubidium, cesium, and the radioactive francium.
