  • @aditya-shukla Fraction can be said as a part of whole thing, which can be written as a ratio of 2 numbers represented as p/q , where p & q are said as numerator and denominator resp.These can be any integer and denominator cannot be zero(0). For example 4/5, -6/17 etc.

    (b) Radical is an atom of an element or a group of atoms of the same or different elements that behave as a single unit and has positive or negative charge.

    (c) Valency is the combining capacity of an atom of an element or of a radical with the atoms of other elements or radicals to form molecules.

    (d) A molecular formula of a compound is the symbolic representation of its one molecule which shows the number of atoms of each element present in it.
