Understanding Transition Metals: Naming and Formulating Ionic Compounds

This guide provides comprehensive insights into transition metals, including their location in the periodic table, oxidation states, and naming conventions for ionic compounds. You'll learn how to write formulas for compounds formed by transition metals and nonmetals, as well as practice exercises for naming and writing chemical formulas, such as Iron (II) Oxide and Copper (III) Nitride. The rules for identifying charges with Roman numerals and naming nonmetals are clearly outlined to help in mastering the chemistry of transition metals.

  1. 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?

  2. Naming Ionic Compounds with Transition Metals

  3. 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

  4. Common Oxidation Numbers for Transition Metals:

  5. 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

  6. Let’s Practice:

  7. 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?

  8. Let’s Practice:

  9. 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
