Atomic structure 2. Isotopes 3. Electron configurations element composed of a single type of atom atomic number equals the number of protons in the nucleus atomic weight (atomic weight) sum of masses of protons, neutrons, and electrons the parts of the atom that interact determining the atom's chemical behavior electrons valance electrons electrons in outermost shell that interact with other atoms isotopes elements that differ in number of neutrons in their nuclei unstable isotopes elements that release energy during radioactive decay chemical bonds when atoms combine by sharing or transferring valence electrons molecule two or more atoms held together by chemical bonds compound a molecule composed of more than one element covalent bond sharing a pair of electrons by two atoms electronegativity attraction of atom for electrons What are the threee prinicipal types of chemical bonds? 1. nonpolar covalent bonds 2. polar covalent bonds 3. ionic bonds hydrogen bonds weak forces that combine with polar covalent bonds nonpolar covalent bonds atoms with similar electronegativities that share electrons that spend an equal amount ot time around each nucleus, no poles exist o
