Question

covalent bonding is typically explained as a bond that forms when atoms are sharing electrons. which statement below explains this concept best?

atoms spend an equal amount of time with each electron before returning it.

atoms are both trying to attract the same electrons, causing a situation where both atoms are pulled together.

atoms with a large atomic radius force smaller atoms to share their electrons.

atoms are attracted to each others electrons, repelling them from each other as they fight over the electrons.

Explanation:

To determine the best explanation for covalent bonding (electron sharing), analyze each option:

• First option: Covalent bonding isn’t about “returning” electrons; it’s sharing, not lending/returning. Eliminate.
• Second option: In covalent bonding, atoms (usually non - metals) attract the same shared electrons, creating a force that pulls them together. This matches the concept of electron sharing leading to bond formation.
• Third option: Covalent bonding is not about “forcing” based on atomic radius; it’s a mutual sharing, often between atoms with similar electronegativities (unlike ionic bonding with transfer). Eliminate.
• Fourth option: If atoms repelled each other, a bond wouldn’t form. Covalent bonding involves attraction due to shared electrons, not repulsion. Eliminate.

Answer:

B. Atoms are both trying to attract the same electrons, causing a situation where both atoms are pulled together.
