Question

Which group of family in the periodic table is most reactive?

Answer 1

Hey mate..!! ☺☺
The group of Alkali Metals is the most reactive group of family in the modern periodic table. the members of the family including: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr).

Answer 2

$\huge \bold {ANSWER}$

◼In the modern periodic table the elements present in group 1 [I A] .

$\bold {PROPERTIES}$

◼The elements present are light metals from Lithuania to Francium.

◼They have one valence electron in the outermost shell and hence are univalent.

◼Alkali metal are strong reducing agents. They are electron donor and have one valence electron in outermost shell, which can easily be removed.

◼The elements are

▶ Highly reactive

▶Highly electropositive.

▶Soft and can be cut with knife.

▶Good conductor of heat and electricity.

◼They form electrovalent compound with non metal.

◼The compounds formed are mostly basic in nature.
