What could two atoms of the same element form?

A. Covalent bonds, but not ionic bonds.

B. Ionic bonds, but not covalent bonds.

C. Both covalent bonds and polar bonds.

D. Either covalent bonds or ionic bonds.

A. covalent bonds only. ionic bonds are between metals and non metals and polar bonds are just more ionic covalent bonds but between different atoms. covalent bonds primarily involve gases and in your case exclusively gases and atoms such as sulfur. Which forms polyatomic molecules called allotropes,the best-known being octasulfur or cyclo-S8
