Which scenario would cause a covalent bond to form?

Answer Details

The scenario that would cause a covalent bond to form is when two atoms share electrons so they can fill their outer shells. In a covalent bond, atoms share electrons to achieve a stable electron configuration, which means having a complete outermost energy level. This sharing of electrons allows both atoms to have a full outer shell, making them more stable and less likely to react with other atoms. Covalent bonds are typically formed between non-metal atoms, as they tend to have a greater affinity for electrons and are more likely to share them with other atoms.
