Document Summary

Covalent bonds: strongest bonds -> sharing a pair of electrons, once formed, rarely break, single, double or triple, cn have partial charges. Hydrogen bonds: hydrogen atom is shared between 2 molecules, have polarity. Ionic bonds: electrons are completely transferred from one atom to another. Van der waals bonds: very weak, form between non polar molecules or non polar parts of a molecule. Reactions: oxidation: elements reacting with oxygen to form oxides, loss of electrons, addition of oxygen, reduction: removal of oxygen from metal ores, gain electrons, lose oxygen, oxidation state/number: sum of negative and positive charges in an atom.
