Refer only to the periodic table on the inside front cover, and arrange the following ionization energies in order of increasing value: for for for for for Mg. Explain the basis of any uncertainties.
Chapter 2: 9/6/2016 Cation and anions Monatomic and polyatomic ions Ionic compounds - Recognizing them and - building a balanced molecular formulas give the exact number of atoms of each element in a compound empirical formulas give the lowest whole number ration of atoms of each element in a compound structural formulas show the order in which atoms are bonded (the connectivity) Oxidation Numbers: the atomic charge of a cation or anion in an ionic compound is also called its oxidation number for a molecular compound the atoms don’t have charges like in ionic compounds 1. pure elements are assigned zero for their oxidation number 2. ions have the oxidation number of their common charge anion- ide cation- ate 3. common oxidation numbers of H, F, and O
