Question

strontium sulfate (srso₄) is composed of strontium and sulfate (so₄²⁻) bonded together. as a mineral, strontium sulfate is called celestine. celestine crystals complete the statement. in celestine, strontium and sulfate are held together by ______ bonds. choose 1 answer: a ionic b covalent c metallic

Explanation:

Strontium is a metal (alkaline - earth metal) and sulfate (\(SO_{4}^{2 -}\)) is a polyatomic anion. Ionic bonds form between metals and non - metals (or polyatomic ions). In the case of \(SrSO_{4}\), strontium (\(Sr^{2+}\)) donates electrons to the sulfate ion (\(SO_{4}^{2 -}\)), resulting in the electrostatic attraction characteristic of ionic bonds. Covalent bonds involve the sharing of electrons (usually between non - metals), and metallic bonds are between metal atoms.

Answer:

A. ionic
