What is the correct name for the ionic compound RbCl?
A
Ruthenium chloride
B
Rubidium chlorate
C
Rhodium chloride
D
Rubidium chloride
Verified step by step guidance1
Identify the elements in the compound RbCl. Rb is the symbol for rubidium, and Cl is the symbol for chlorine.
Determine the type of compound. Since Rb is a metal (an alkali metal) and Cl is a nonmetal, the compound is ionic.
Name the cation (positive ion) first. The cation is rubidium, so use the element name 'rubidium' directly.
Name the anion (negative ion) second. For chlorine as an anion, change the ending to '-ide', resulting in 'chloride'.
Combine the names of the cation and anion to get the full name: 'rubidium chloride'.
