What is the correct name for the ionic compound with the formula RbF?
A
Radium fluoride
B
Rubidium fluorine
C
Ruthenium fluoride
D
Rubidium fluoride
Verified step by step guidance1
Identify the elements in the formula RbF. Rb stands for rubidium, and F stands for fluorine.
Determine the type of compound. Since Rb is a metal (an alkali metal) and F is a nonmetal, the compound is ionic.
Name the cation (positive ion) first. The cation is rubidium, so use the element name 'rubidium' as is.
Name the anion (negative ion) second. For fluorine, the anion name changes to 'fluoride' by replacing the '-ine' ending with '-ide'.
Combine the names of the cation and anion to get the full name of the ionic compound: 'rubidium fluoride'.
