Answer 2

A radical is a group of atoms which can combine with other element as a single unit. Each radical takes part as a whole in chemical reaction and has its own valency.Valency is the no. of hydrogen atoms that can combine with one atom of an element or radical to form a compound.valency of an element is a whole number. Radicals with valency 1 are monovalent, with valency2 are divalent, with valency 3 are trivalent. all non metals and nonmetallic radicals have negative valency
