Naming and Charges of Iron Compounds

The video tutorial explains how to name the compound FeP by identifying iron as a transition metal and phosphorus as a non-metal. It details the process of naming the metal and non-metal using the periodic table, replacing the non-metal's ending with 'ide', and determining the charge of the transition metal. The final name, iron(III) phosphide, is derived by balancing the charges of iron and phosphorus.

What type of metal is iron in the compound FeP?

• Non-metal

• Transition metal

• Alkaline earth metal

• Alkali metal

What is the first step in naming the compound FeP?

• Replace the suffix of the non-metal with 'ide'

• Write the name of the metal as it appears on the periodic table

• Determine the charge of the metal

• Write the name of the non-metal

How is the suffix of the non-metal changed when naming FeP?

• Replace 'phosphorus' with 'phosphate'

• Replace 'phosphorus' with 'phosphor'

• Replace 'phosphorus' with 'phosphorate'

• Replace 'phosphorus' with 'phosphide'

What charge does phosphorus typically have in compounds?

• 4-

• 3-

• 2+

• 1+

What Roman numeral is used to indicate the charge of iron in iron(III) phosphide?

• IV

• II

• III

• I

If given the name iron(III) phosphide, what would be the charge of the iron ion?

• 4+

• 2+

• 3+

• 1+
