What is the rule with transition metals?

• Trick question, no special rule

• Write the charge next to the name in number form

• Write the charge next to the name in roman numeral form

When naming a transition metal ion that can have more than one common ionic charge, the numerical value of the charge is indicated by a 

• prefix
• suffix
• Roman numeral following the name
• superscript after the name

Roman numerals tell you the ____ of the metal cation(s) in an ionic compound.

• number
• mass
• type
• charge

An -ate or -ite at the end of a compound name usually indicates that the compound contains

• fewer electrons than protons
• neutral molecules
• only two elements
• a polyatomic ion

Which of the following would require a Roman Numeral in its name?

• Al₂O₃
• Na₂S
• CuSO₄
• Sr(ClO₃)₂

What is the correct name for this formula; BeI₂?

Hint (What group is Be (Beryllium) found in? Does it have one charge or more than one?)

• beryllium (II) iodide

• beryllium diiodide

• beryllium iodine

• beryllium iodide
