Sort the following atoms into metals and nonmetals. Th en name three ionic compounds

Chapter 7- Chemical Bonding and Molecular Geometry 1) Types of bonds a) Ionic i) Salts with negative and positive charges. These are soluble in water. b) Polar Covalent i) Dipole forces are like magnets, they stick everything together. c) Pure Covalent i) If they aren’t the exact same atom, they aren’t pure. 2) How many electrons does an atom need a) Look at table 7.1 in book. b) Lewis structure only takes into account outer shell, called valence electrons. 3) Valence Electrons a) The number of electrons present in the outermost shell b) MOst important electros when considering bonding. 4) Writing Lewis Structures- Rules a) Draw a skeleton structure for the sp
