Naming and Charges of Transition Metals

The video tutorial explains how to name the compound MnS2. It begins by identifying manganese as a transition metal and sulfur as a non-metal. The process involves writing the names as they appear on the periodic table, modifying the non-metal's suffix to 'ide', and determining the charge of manganese. Since manganese is a transition metal, its charge is indicated with a Roman numeral. The tutorial concludes with the name 'manganese(IV) sulfide', explaining how to balance the charges between manganese and sulfide ions.

What type of metal is manganese in the compound MnS2?

• Alkaline earth metal

• Alkali metal

• Noble gas

• Transition metal

What is the first step in naming the compound MnS2?

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

• Write the name of the non-metal

• Determine the formula from the name

• Identify the charge of the metal

How is the name of the non-metal modified when naming MnS2?

• Add 'ate' to the end

• Add 'ite' to the end

• Leave it unchanged

• Change the ending to 'ide'

Why is it necessary to include the charge of manganese in the name of MnS2?

• Because sulfur is a transition metal

• Because manganese is a non-metal

• Because manganese is a transition metal

• Because sulfur is a non-metal

What is the ionic charge of the sulfide ion in MnS2?

• 3-

• 4-

• 2-

• 1-

What is the charge of manganese in MnS2?

• 5+

• 2+

• 3+

• 4+

What Roman numeral is used in the name of MnS2 to indicate the charge of manganese?

• II
