Lesson Three--Transition Metal Compounds Concept: Transition metals have electrons in d orbitals and can

Lesson Three--Transition Metal Compounds Concept: Transition metals have electrons in d orbitals and can donate different numbers of electrons, thus giving them several different positive charges. Fact 10: These can be determined from the Roman numeral which is written next to the metal's name. Example: Cu 1+is Copper I Pb 2+is Lead II Fe 3+is Iron III Sn 4+s Tin IV

Transition Metal Compounds Fact 11: These transition metals are used in formulas just like

Transition Metal Compounds Fact 11: These transition metals are used in formulas just like other metals, once the charge is determined from the Roman numeral in the name. Example: Cu 1+ Cl 1 Pb 2+O 2 Fe 3+Br 1 -3 Sn 4+O 2 -

Transition Metal Compounds Fact 11: Roman numeral in the name. Example: Cu 1+ Cl

Transition Metal Compounds Fact 11: Roman numeral in the name. Example: Cu 1+ Cl 1 copper (I) Pb 2+O 2 Fe 3+Br 31 Sn 4+O 2 - Lead Iron

Transition Metal Compounds Fact 12: A few transition metal ions only have one charge

Transition Metal Compounds Fact 12: A few transition metal ions only have one charge and never change so they can be written without a Roman numeral in their formula name. Example: Ag 1+ Zn 2+ Cd 2+

Names of Variable Ions Use a roman number after the name of a metal
