What values of J may occur in the terms (i) \({ }^{1} \mathrm{~S}\), (ii) \({ }^{2} \mathrm{P}\), (iii) \({ }^{3} \mathrm{P}\)? How many states (distinguished by the quantum number \(M_{J}\)) belong to each level?

Spencer Kociba CHEM 101 Lecture notes Lecture 10/18/16 BONDS AND COMPOUNDS ● Types of bonds ○ Ionic: when a metal and a nonmetal bond (electron is transferred from one element (usually the metal) to the other). This produces a charge and makes ionically bonded substances highly conductive ■ Electrostatic attraction between a cation and an anion ■ Remember: an ION is a CHARGED particle −¿ ¿ ■ Ex. +¿Cl❑ Na❑ ¿ ○ Covalent: when two nonmetals bond (the electron(s) are shared between the elements). This produces no charge and covalently bonded substances are of low conductivity. ■ Ex. CH❑ 4 ● Lewis Dot Structure ○ Representation of an atom’s valence electrons. Indicates how the valence electrons are distributed in a molecule ○ ○ Octet rule ■ An atom is most stable when its outermost shell of electrons is empty/full ● This does NOT include transition metals in the d block ● Representing Molecules ○ Molecular formula: a formula t
