Transition Metals Study Notes

Transition Metals Overview

  • Focus on Type 2 binary compounds with transition metals (variable charge).

Characteristics of Transition Metals

  • Transition metals change their charge and valence electrons.
  • Located in the middle of the periodic table.

Charge Exceptions

  • Silver: always +1
  • Palladium: always +2
  • Zinc: always +2

Determining Charges

  • Charges of transition metals depend on the nonmetals they are bonded to.
  • For example, oxygen is consistently -2.

Naming Conventions

  • Use Roman numerals to indicate charge:
    • I = +1
    • II = +2
    • III = +3
    • IV = +4
    • V = +5
    • VI = +6
    • VII = +7
    • VIII = +8
    • IX = +9
    • X = +10

Example Problem

  • For lead oxide, if oxygen has a charge of -2:
    • Lead charge determined based on balancing the compound to neutral.
    • Lead(II) oxide means lead is +2.
    • If two oxygen atoms are present (each -2), lead must be +4 for neutrality.

Compound Naming from Formula

  • Example: Manganese (Mn) with -2 charge oxygen may give charge of +7.
  • Balance for neutral compound; consider multiple manganese ions if needed (e.g., 2 Mn for 7 O).
