Naming Ionic Compounds with Transition Metals

Why are transition metals considered unpredictable?

• They do not react with other elements.

• They have multiple oxidation numbers.

• They are always in a gaseous state.

• They have a fixed oxidation number.

What is the oxidation number for Group 1 metals?

• +1

• +2

• 0

• +3

How do we indicate the oxidation number of a transition metal in a compound?

• Using a Roman numeral in parentheses

• Using a prefix

• Using a Greek letter

• Using a subscript number

What does the Roman numeral (II) in cobalt (II) chloride signify?

• The number of chlorine atoms

• The second oxidation state

• The oxidation number +2

• The atomic number of cobalt

If a compound has cobalt and three chlorine atoms, what is the oxidation number of cobalt?

• +4

• +2

• +1

• +3

What is the general oxidation number for chlorine when paired with a metal?

• -2

• -1

• +2

• +1

In the Stock system, what does the Roman numeral indicate?

• The position of the metal in the periodic table

• The number of atoms in the compound

• The oxidation number of the metal

• The atomic mass of the metal

What is the oxidation number of cobalt in cobalt (III) chloride?

• +1
