5 Questions
What are the elements placed in the IA group of the Periodic Table and why?
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.
What are alkali metals and why are they called so?
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.
What is the electronic configuration of alkali metals?
The electronic configuration of alkali metals follows the pattern: [noble gas] ns^1, where n represents the principal quantum number of the electron shell.
What is the occurrence of alkali metals in nature?
Alkali metals do not occur in free state in nature. They are highly reactive and are usually found in compounds.
What is the nature of alkali metals in terms of physical properties?
Alkali metals are soft, have low melting and boiling points, and are highly reactive.
