Document Summary
Mass - a measure of the quantity of matter in an object. On earth, equivalent to the weight of an object. Chemical bonding - general term for a bond created when electrons of two atoms interact and rearrange into a new form that allows the atoms to become attached to each other. Ionic, covalent, and hydrogen bonds are all chemical bonds. Molecule - an entity consisting of a defined number of atoms covalently bonded together in a defined spatial relationship. Electronegativity - the measure of the strength of attraction an atom has for electrons that are being shared in a covalent bond. An atom with higher electronegativity will tend to pull electrons toward itself, away from atoms with lower electronegativity. Polar covalent bond - a type of covalent bond in which electrons are shared unequally between atoms, so that one end of the molecule has a slight negative charge and the other end a slight positive charge.
