Document Summary

Atoms tend to gain or lose electrons until they have achieved an outer shell that contains an octet of electrons (8) Electrons are removed from the outermost shell of an atom or ion first. Electrons are moved from the highest energy subshell. Electrons are first added to partially filled subshells with the lowest value of n. Elemental symbols with dots which allow us to keep track of valence electrons. One dot is placed on each side of the element symbol, each side is equivalent, up to. Remaining dots are added to each side. Each side can hold up to 2 dots, each side is equivalent. Two h atoms begin far apart, electron clouds are normal. As they move closer, the electron clouds become distorted due to nuclear attraction. When fairly close, the electron clouds blend together into one electron cloud. In h2, the two electrons are shared by both h atoms, creating a covalent bond.
