Kyle Paulk SI CHEM 1201: Office Hours: Molecules and Ionic Compounds A contains at least 2 atoms of different elements or the same element. i.e. O 2 , CO, CH 4 A is typically formed from a metal and a nonmetal and is held together by electrostatic interactions between oppositely charged ions. i.e. NaCl Ions Positive charge is achieved when an atom electrons. Negative charge is achieved when an atom electrons. Main group metals commonly adopt positive charges equal to the . The metals often adopt a charge of +2, but +1 and +3 are also common. Anions are formed by or groups of atoms (poyatomic). **Memorize table of ions** Some good ones to know CH 3 COO - OH - O 2- N 3- HCO 3 - HSO 4 - HPO 4 2- H 2 PO 4 - Periodic Table What are the elements in group VII called? How many electrons do they lack to achieve an octet? What charge do they adopt? What are the elements in group VIII called? How many electrons do they need to achieve an octet? What charge do they adopt?
