Detailed explanation-1: -Expert-Verified Answer. The alkali metals can be regarded as elements that falls at group 1 of the periodic table, they are very reactive.
Detailed explanation-2: -The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Detailed explanation-3: -Hence only option (c) is true for all the alkali metals. Q. Alkali metals react with water vigorously to form hydroxides and dihydrogen.
Detailed explanation-4: -Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Detailed explanation-5: -All bases do not dissolve in water. An alkali is a base that dissolves in water. Hence Statement 2 is correct.
