Answer:
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).

sodium is soft metal

Sodium is a soft, silvery metal that reacts very vigorously with water, and tarnishes easily in air. It is the fourth most abundant element in the Earth's crust, which consists of 2.6% sodium by weight; seawater is about 1.5% sodium.
