Here's how to break down the name:
* Sr: This symbol represents the element strontium.
* Br: This symbol represents the element bromine.
* 2: The subscript "2" indicates that there are two bromine atoms for every strontium atom in the compound.
Since strontium is a metal and bromine is a nonmetal, this compound is an ionic compound. The name simply combines the name of the metal (strontium) with the name of the nonmetal (bromine), adding "-ide" to the end of the nonmetal's name.
