Polyatomic ions
Ions that are formed when a group of atoms gains or loses electrons.
VESPR
Valence Shell Electron Pair Repulsion
Guiding principle behind VESPR theory
Groups of electrons try to get as far apart from one another as possible.
Non-polar Covalent Bond
A covalent bond in which the electrons are shared equally between the atoms involved.
Polar Bond
A covalent bond in which the electrons are shared unequally between the atoms involved.
Non-polar molecule
A covalent molecule in which the electrons are evenly distributed throughtout the whole molecule.
