Document Summary

Water and ocean structure: water, water molecules and chemical bonds, molecule a group of atoms held by chemical bonds, the chemical formula of water is h2o, chemical bonds when electrons are shared or exchanged between atoms. Ionic bonding exchange of electrons: covalent bonding sharing of electrons, covalent bonds bonds formed by shared pairs of electrons, ex. Universal solvent: pulls apart ionic bonds due to its polarity: ex. Tendency of water to spread through a material (ex. towel: thermal properties, a.
