Final answer:
Sr₃(PO₄)₂ is composed of strontium (Sr), phosphorus (P), and oxygen (O), and the compound includes three strontium atoms, two phosphorus atoms, and eight oxygen atoms.
Step-by-step explanation:
The elements that make up Sr₃(PO₄)₂ are strontium (Sr), phosphorus (P), and oxygen (O). The subscript numbers in the chemical formula indicate the number of each atom present in the compound. Strontium has a subscript of '3', indicating there are three strontium atoms.
The (PO₄) part is the phosphate group, which contains one phosphorus atom and four oxygen atoms. Since there are two phosphate groups in Sr₃(PO₄)₂, we multiply the numbers of phosphorus and oxygen in one phosphate group by two, resulting in two phosphorus atoms and eight oxygen atoms.
Overall, Sr₃(PO₄)₂ consists of three strontium atoms, two phosphorus atoms, and eight oxygen atoms.
The compound Sr₃(PO₄)₂ is composed of the elements strontium (Sr) and phosphate (PO₄). In this compound, there are three strontium atoms (Sr) and two phosphate ions (PO₄²⁻). The formula indicates that there are three strontium ions and two phosphate ions in the compound.
