    A chemical symbol is a character or notation of one or two letters representing a chemical element which are assigned to designate new or to-be-synthesized elements.

    Formulas are concise way of expressing information symbolically.

    An Atom is the smallest part of a substance can take part in a chemical reaction.

    mixtures are substances made up of two or more different elements or substances in which the identities are retained and are in the form of solution.

    A chemical element is a combination of an atom having the same number of protons in their atomic nuclei.

    An ion is a charged atom or molecule. It is charged because the number of electrons are not equivalent to the number of protons in the atom or molecule.

    A compound is a substance formed when two or more chemical elements are chemically bonded together. Examples of compounds are water, sand, urea, urine etc.
