Created with Fabric.js 1.4.5 FORMULAWRITING NAMING FORMULAWRITING Sodium ChlorideCalcium CholridePotassium Bromide Use the prefixes in the nameto tell you the subscript of each element in the formula.Ex. CO2 NAMING Write the symbols for the ions side by sideWrite the cation first. Crisscross the chargesby using the absolute value of each ion'scharge as the subscript for the other ionSimplify the subscripts if possible. Ex. NaCl Name the cation first, followed by the anion. Be sure the anion ends in -ide. Remember to use Roman Numerals for those metals with more than one charge.Ex. Calcium Chloride Metal (cation) and Nonmetal (anion)Solid at room temperatureHigh melting pointSolid not conductive, but liquid is The chemical bond that results from sharing valence electrons DEFINITION PROPERTIES EXAMPLES EXAMPLES DEFINITION WaterAmmoniaMethane The electrostatic force that holds oppositely charged particles together in an ionic compound Ionic vs Covalent PROPERTIES Use prefixes to indicate the number of each atom. The first element includes the prefix and the element name. The second includes the prefix, element name, and an -ide ending.Ex. Dinitrogen Monoxide Gases, liquids, and solids at room temperatureLow melting and boiling pointsNot conductive in all states Bonds By Sarah Coughlin If the difference between the electronegativities of the atoms are between 0.0 and 1.7, the bond is covalent. If the difference is 1.7 or greater, the bond is ionic.
