what is the name of the compound with the chemical formula of sri₂?
sulfur iridium
sulfur diiridium
strontium diiodide
strontium iodide

Explanation:

• Identify the elements: In \(SrI_2\), \(Sr\) is strontium (a metal) and \(I\) is iodine (a non - metal).
• Name the compound: For ionic compounds (metal + non - metal), the metal name comes first. The suffix for the non - metal is “-ide”. Since there are two iodine atoms, we use the prefix “di -” for the non - metal part in the naming convention of binary ionic compounds.

Answer:

Strontium diiodide
