Ionic Compounds and Their Properties

The video tutorial explains how to name the compound PBO by identifying it as an ionic compound composed of lead (a metal) and oxygen (a non-metal). It discusses the importance of considering ionic charges, as lead can have different charges (Pb2+ or Pb4+), while oxygen is always -2. The tutorial explains how to balance these charges to form PBO or PBO2 and highlights the need to use Roman numerals to differentiate between the two compounds when naming them, resulting in 'lead(II) oxide' for PBO.

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

• Metallic compound
