Binary Ionic Compounds and Naming

The video tutorial explains how to name the compound K3N, identifying it as a binary ionic compound. It details the steps to name the metal and non-metal components, resulting in the name potassium nitride. The tutorial also covers how to write the chemical formula from the name, considering the ionic charges of potassium and nitrogen. Dr. B concludes the session with a summary of the naming process.

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

• Metallic compound

• Ionic compound

• Covalent compound

• Organic compound

What is a binary ionic compound?

• A compound with three elements

• A compound with two different elements

• A compound with two non-metals

• A compound with two metals

How do you determine the name of the metal in a binary ionic compound?

• By writing it as it appears on the periodic table

• By using its molecular weight

• By using its atomic number

• By using its chemical symbol

What suffix is used for the non-metal in a binary ionic compound?

• -ite

• -ous

• -ide

• -ate

What is the name of the compound K3N?

• Potassium nitride

• Potassium nitrate

• Potassium nitrogen

• Potassium nitrite

What is the ionic charge of potassium in K3N?

• 0

• 3+

• 1+

• 2+

Why are three potassium ions needed to balance one nitride ion in K3N?

• Because potassium has a 2+ charge

• Because nitrogen has a 1- charge

• Because potassium has a 1+ charge and nitrogen has a 3- charge

• Because nitrogen has a 2- charge
