Naming and Charges of Tin Compounds

The video tutorial explains how to name the compound Sn3N4. It starts by identifying the metal as tin and the nonmetal as nitrogen. The nonmetal's suffix is changed to 'ide' to form 'tin nitride.' Since tin is a transition metal, its charge must be specified. The video calculates the charges, showing that tin has a 4+ charge, leading to the name 'tin(IV) nitride.' The tutorial also explains how to deduce the formula from the name.

What is the first step in naming the compound Sn3N4?

• Identify the nonmetal from the periodic table.

• Identify the metal from the periodic table.

• Determine the charge of the metal.

• Determine the charge of the nonmetal.

How is the name of the nonmetal modified in the compound Sn3N4?

• By adding 'ium' to the end.

• By adding 'ite' to the end.

• By adding 'ate' to the end.

• By adding 'ide' to the end.

Why is it necessary to include the charge of tin in the name of Sn3N4?

• Because tin is a transition metal.

• Because tin is an alkali metal.

• Because tin is a noble gas.

• Because tin is a nonmetal.

• 2-

• 3-

• 4-

• 1-

How many nitride ions are present in Sn3N4?

• Four

• Three

• Five

• Two

What is the charge of each tin ion in Sn3N4?

• 2+

• 3+

• 4+

• 5+

What does the Roman numeral in the name 'tin four nitride' indicate?

• The number of tin atoms.

• The charge of the tin ion.

• The number of nitrogen atoms.

• The charge of the nitrogen ion.

If given the name 'tin four nitride', how can you determine the formula?

• By counting the number of tin atoms.

• By knowing the atomic mass of tin.

• By counting the number of nitrogen atoms.

• By knowing the charge of tin and balancing it with nitride ions.
