CHEM 124 Midterm: Exam 2 Review - F19
Document Summary
Ionic bonds are described as the results of the transfer of electrons; they tend to form between metals and non-metals. Covalent bonds are described as the sharing of electron pairs; they tend to form between non- metals and non-metals. Metallic bonding is described as a pooling of the valence electrons of the metal that creates a mobile sea of electrons that can flow and keep the metal atoms together. To name a binary ionic compound, we name the cation first and the anion second. If the cation is one that can have more than one charge, write the charge of the ion in the compound in parentheses after the cation. In compounds with polyatomic ions (usually anions), use the name of the polyatomic ion in the appropriate place (first, if it is a cation, second if it is an anion). The total charges of all the ions in an ionic compound must add up to an overall charge of zero.
