Solution: Use the appropriate naming convention (for ionic or molecular substances) to assign a name to each of the compounds PbCl4 and RbCl.

Problem

Use the appropriate naming convention (for ionic or molecular substances) to assign a name to each of the compounds PbCl4 and RbCl.

Solution

We are asked to use the appropriate naming convention (for ionic or molecular substances) to assign a name to each of the compounds PbCl4 and RbCl.

To do so, we shall do the following steps:

Step 1: Determine if the compound is an ionic or molecular substance.

Step 2: Determine the name of the given compound.

Let’s first define an ionic and molecular bond:

Ionic Bond

involves the transferring of an electron from one element to another element
positively charged ion + negatively charged ion

metal → usually is the positively charged ion (+)
nonmetal → usually is the negatively charged ion (-)
metal(or polyatomic ion) + nonmetal (or polyatomic ion)


Covalent (or Molecular) Bond

involves the sharing of electron(s) between elements

nonmetal + nonmetal
