Alkali Metals Quiz

The elements placed in the IA group of the Periodic Table are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). They are placed in this group because they have one electron in their outermost orbit and show one valency.

Alkali metals are the elements in the IA group of the Periodic Table. They are called alkali metals because they react with water to form hydroxides, which are strong alkalies or bases soluble in water.

The electronic configuration of alkali metals follows the pattern: [noble gas] ns^1, where n represents the principal quantum number of the electron shell.
