Monday, January 13, 2014 Warm Up: Write the Formulas: Sodium/Chlorine Calcium/Sulfur Aluminum/Nitrogen Write the Names: BeBr2 K3P B2O3 Write the Formulas: Lithium Phosphide Cesium Sulfide Barium Bromide Where do you find the transition metals?
Transition Metals: • Metals found in the D-block on the periodic table • Get there name because most do NOT have only 1 oxidation state like the metals in S and P blocks. • Most have 2 or more oxidation states that they transition in and out of. Fe+2 and Fe+3
Rules for naming Transition Metals: • The name of the metal ALWAYS comes first: • The metal’s name is as it is on the periodic table • Identify the metals charge with Roman Numerals • The name of the nonmetal ALWAYS comes second. • Change the ending of the nonmetal to “ide” • Unswap and Undrop • Bring the subscripts back up to the opposite element (the elements should now have their actual oxidation number) • Double check the nonmetals (anions) oxidation number to make sure it is what it is supposed to be. FeCl3
Naming transition metals: • Name the metal • Name the nonmetal • Unswap and Undrop • Check the oxidation number FeO Fe+1 O-1 Oxygen’s oxidation number is -2. 5. Multiply to get Oxygen to it’s -2 oxidation number - multiply both Fe and O by 2 to get: Fe+2 and O-2 6. Now name it: Iron (II) Oxide What is Oxygen’s oxidation number?
Writing Compounds from the Name with Transition Metals: • Write out the ions and their charges for each element • Remember the charges for the transition metals is written in Roman Numerals • Drop the signs • Swap the numbers • Simplify if needed Copper (III) Nitride Cu+3 N-3 Cu3N3CuN
