Notes for atoms and molecules
WebAtoms chemically bond together to form molecules, and the composition of a molecule is given by its chemical formula (O 2, H 2 O, C 6 H 12 O 6 ). When the atoms in a molecule are different, the molecule is a compound (H 2 O and C 6 H 12 O 6, but not O 2 ). WebA collection of molecules is called a compound. Summary An atom has negatively-charged electrons in orbit around its nucleus, which is composed of positively-charged protons and neutrons, which have no charge. An atom that gains or loses electrons is an ion. Positively charged ions are cations, negatively charged ions are anions.
