CAS CH 102 Chapter Notes - Chapter 4: Barium Chloride, Iron(Ii) Chloride, Ionic Bonding
Document Summary
Chapter 4: structure and properties of ionic and covalent compounds. Ionic bond - a transfer of one or more electrons from one atom to another. Covalent bond - attractive force due to the sharing of electrons between forms attractions due to the opposite charges of the atoms. atoms: essential features of ionic bonding. Atoms with low i. e. and low e. a. tend to form positive ions. Atoms with high i. e. and high e. a. tend to form negative ions. The ions are held together by the electrostatic force of the opposite. Ion formation takes place by electron transfer. charges. Reactions between metals, and metals and nonmetals (representative) tend to be ionic: covalent bonding. Let"s look at the formation of h2. Each hydrogen has one electron in it"s valance shell. However, both hydrogen atoms have the same tendency to gain or lose. If it were an ionic bond it would look like this: electrons. Both gain and loss will not occur.
