Chapter 2: Q64P (page 83)

Are molecules present in a sample of BaF2? Explain.

Short Answer

Expert verified

There are no molecules present in a sample of BaF2 because it is an ionic compound.

Step by step solution

01

Define ionic compounds

An ionic compound is a chemical compound made up of ions kept together by electrostatic forces known as ionic bonding. The net charge of ionic compounds is neutral (zero), although it contains both positively and negatively charged ions known as cations and anions.

02

Find the type of compound

The sample of BaF2containsbarium cations (metals) and fluoride anions.Because cations and anions create a strong electrostatic interaction between them to form ionic bonds. Therefore, the sample of BaF2 has no molecules.
