Question

Explain the difference between a covalent bond formed between two atoms of the same element and a covalent bond between two atoms of two different elements.

Answer 1

Polarity

Step-by-step explanation:

Covalent bonds between two atoms of the same element (diatomics) are nonpolar because neither atom is more electronegative. Covalent bonds between atoms of two different elements are often polar and must be polar to some extent because of differences in electronegativity between the two atoms involved.
