what is the name of the ionic compound rbcl?
Best Answer: First, let's start with naming binary ionic compounds. A binary ionic compound has one metal and one nonmetal present in the compound. Let's consider my username (rubidium.chloride) as an example. Rubidium chloride, or RbCl, is a binary ionic compound. The metal here is Rb (rubidium, group 1A) and the nonmetal is Cl (chlorine, group 7A). When you name binary ionic compounds, you mention the cation (positively charged ion) first (usually metals, those elements that appear on the left side of the periodic table have the tendency to form positively-charged ions). Then mention the anion (negatively charged ion). The cation is rubidium (Rb).
