Naming and Charges of Ionic Compounds

The video tutorial explains how to name and write the formula for the ionic compound MgS. It begins by identifying MgS as a binary ionic compound composed of a metal (magnesium) and a non-metal (sulfur). The tutorial outlines the steps to name the compound: first, write the name of the metal as it appears on the periodic table, then write the name of the non-metal with the suffix 'ide'. The video also covers how to write the chemical formula by balancing the ionic charges of magnesium (2+) and sulfide (2-) to achieve a net charge of zero, resulting in the formula MgS.

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

• Organic compound

• Metallic compound

• Ionic compound

• Covalent compound

What is the first step in naming a binary ionic compound?

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

• Determine the charge of the metal

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

• Write the name of the non-metal

How do you modify the name of the non-metal in a binary ionic compound?

• Keep the name unchanged

• Replace the ending with 'ide'

• Add 'ite' to the end

• Add 'ate' to the end

What is the correct name for the compound MgS?

• Magnesium sulfide

• Magnesium sulfur

• Magnesium sulfate

• Magnesium sulfite
