Recap - Material Match

Part of the Structure and Bonding section of Coddy's Chemistry journey. Lesson 38 of 49.

Challenge

A lab tests a grey powder found in a mine. It burns in air with a bright white flame, and the ash is a mixture of magnesium oxide and magnesium nitride, a hard ionic solid that melts above 1500 °C. Build the neutral formula of magnesium nitride from its ions.
