Question

which statement(s) is/are true about covalent bonds? select all that apply a covalent bonds can form between two metal atoms. b covalent bonds can form between atoms of different elements. c covalent bonds can form between a metal atom and a nonmetal atom. d covalent bonds can form between atoms of the same element. e covalent bonds can form between two nonmetal atoms.

Explanation:

Covalent bonds are formed by the sharing of electron pairs between atoms. They commonly form between non - metal atoms (option e), but can also form between atoms of the same non - metal element (e.g., $O_2$, option d) and between atoms of different non - metal elements (option b). While it is less common, in some cases covalent bonds can form in compounds involving metal atoms in complex molecules, but typically covalent bonds are not the primary bond type between two metal atoms.

Answer:

B. Covalent bonds can form between atoms of different elements.
D. Covalent bonds can form between atoms of the same element.
E. Covalent bonds can form between two nonmetal atoms.
