Lewis Dot Structure

Back

A diagram showing the valence electrons of atoms as dots around the element symbols to illustrate bonding.

Back

Chemical compounds composed of exactly two different elements, often formed by ionic or covalent bonds.

Front

Products

Back

Substances formed as the result of a chemical reaction.

Front

Reactants

Back

Starting substances that undergo a chemical change during a reaction.
