A chemical symbol is the short version of the chemical name given to an element. The chemical symbol appears on the Periodic Table, is 1 or 2 characters long and is derived from the Latin name of the particular element.

As an example, Gold's chemical symbol is Au, which stands for the Latin word "Aurum".

A chemical formula is an abbreviated description of a compound, with a compound being a chemical made from more than one single element. The formula uses the chemical symbols, in a precise pattern that follows the make-up of the compound, to accurately describe the chemical's elemental and electrical structure.

An example of a compound, or chemical formula, is H2O. 2 parts Hydrogen to 1 part Oxygen. The H is the element (or symbol), as is the O, whereas the H20 is the formula (or compound).

What is the electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond?

The electronegativity equation used to calculate the difference in electronegativity between two atoms in a chemical bond is the absolute difference between the electronegativity values of the two atoms. This is represented as A - B, where A and B are the electronegativity values of the two atoms.
