Created with Fabric.js 1.4.5 *Involves the transfer of electrons *Electrostatic attraction between a cation (metal) and an anion (nonmetal)* Attraction between a positively and negatively charged atom* Difference in electronegativity 1.7 or greater Name the cation then the anion* If the cation is a transition metal with more than one charge, name the metal then use a Roman numeral to indicate the charge * On the anion drop the ending and add -ide* May include Polyatomic ions (group of ions electrically charged; treated as a single group) ie. HCl~ Hydrogen Chloride ~Used to create chlorides and fertilizers CuS~ Copper II Sulfide CaSO3~ Calcium Sulfite Name the two nonmetals and add the appropriate prefixes to show how many of each element is present * If there is only one of the first element, a prefix is not included * Drop the ending and -ide to the end of the second nonmetal ie. CO2~ Carbon dioxide ~Used in carbonated drinks N2O4~ Dinitrogen Tetroxide ~Used as rocket propellant *Results from the sharing of electrons to form a stable octet*Attraction between a metal and another metal* Can form single, double, or triple bonds between atoms * Difference in electronegativity 0.0-1.7** Nonpolar bond if difference in electronegativity 0.0-0.3** Polar bond if difference in electronegativity 0.4-1.7 Ionic vs. Molecular Bonds 1. Write the symbol and charge of the cation2. Write the symbol and charge of the anion 3. Crisscross charges and write correct subscripts 4. Write formula in simplest termsie. Lead II Nitride~ Pb3N2 Calcium Nitrate~ Ca(NO3)2Magnesium Hydroxide~ Mg(OH)2~Used as an over-the-counter drug; treats heartburn, constipation, etc. Sodium Chloride~ NaCl~Table salt, used to flavor and preserve food 1. Write both nonmetals2. Write the subscripts that correspond with the prefix * Formula doesn't have to be simplified ie. Selenium Hexafluoride~ SeF6Dinitrogen Tetrachloride~ N2Cl4Dihydrogen Oxide~ H2O ~Water * Results from the sharing of electrons to form a stable octet * Attraction between two nonmetals * Can form single, double, or triple bonds *Can be Polar or Nonpolar **Polar- unequal sharing; difference in electronegativity 0.4-1.7 **Nonpolar- unequal sharing; difference in electronegativity 0.0-0.3 Morgan Hopkins Morgan Hopkins
