Why do atoms bond with each other?

• A. To achieve a more stable electron configuration, often by attaining a full valence shell
• B. To lose all of their electrons
• C. To increase their atomic number
• D. To become radioactive

Answer: (A)

Verified step by step guidance

1. Understand that atoms bond with each other primarily to achieve greater stability in their electron arrangement.
2. Recall that atoms are most stable when they have a full valence shell, which usually means having eight electrons in their outermost shell (the octet rule), except for some elements like hydrogen and helium.
3. Recognize that atoms can achieve this stable configuration by sharing, gaining, or losing electrons through different types of chemical bonds (covalent, ionic, or metallic bonds).
4. Note that losing all electrons or increasing atomic number are not reasons for bonding; these processes relate to ion formation or nuclear reactions, respectively.
5. Conclude that the fundamental driving force for bonding is to reach a more stable electron configuration, often by filling the valence shell.
