Question

Which elements will share electrons when a bond is formed between them?

1) ba and i
2) c and cl
3) li and i
4) he and o

Answer 1

Ba and I, C and Cl, Li and I, and He and O form covalent bonds by sharing electrons to achieve a stable electron configuration.

Step-by-step explanation:

The elements that share electrons when a bond is formed between them are:

1. Ba and I
2. C and Cl
3. Li and I
4. He and O

In these examples, ba (barium) and i (iodine), c (carbon) and cl (chlorine), li (lithium) and i (iodine), and he (helium) and o (oxygen) form covalent bonds by sharing electrons to achieve a stable electron configuration. In a covalent bond, atoms share electrons to fill their valence shells and become more stable.
