Ionic Compounds and Lithium Chemistry

The video tutorial explains how to name the compound Li3N by identifying it as an ionic compound composed of lithium, a metal, and nitrogen, a non-metal. The process involves writing the name of the metal as it appears on the periodic table and modifying the non-metal's name by replacing its ending with 'ide'. The tutorial also covers how to write the formula for lithium nitride by balancing the charges of lithium ions (1+) and nitride ions (3-), resulting in the formula Li3N.

What type of compound is formed when a metal and a non-metal combine?

• Covalent compound

• Ionic compound

• Metallic compound

• Organic compound

When naming an ionic compound, which component's name is written first?

• The element with the lower atomic number

• The metal

• The non-metal

• The element with the higher atomic number

How is the name of the non-metal modified in an ionic compound?

• By adding 'ate' to the end

• By adding 'ium' to the end

• By adding 'ide' to the end

• By adding 'ite' to the end

What is the name of the compound Li3N?

• Lithium nitrite

• Lithium nitrogen

• Lithium nitride

• Lithium nitrate

If lithium forms ions with a 1+ charge, how many lithium ions are needed to balance one nitride ion with a 3- charge?

• 3 lithium ions

• 4 lithium ions

• 2 lithium ions

• 1 lithium ion

What is the chemical formula for lithium nitride?

• LiN

• Li2N

• Li3N

• Li4N
