Why do atoms gain, lose, or share electrons?
Understand the Problem
The question is asking for an explanation of the behavior of atoms regarding their electrons. It seeks to understand the reasons behind atoms gaining, losing, or sharing electrons, which is fundamental to chemical bonding and reactions.
Answer
To attain a stable electronic configuration.
Atoms gain, lose, or share electrons in order to attain a stable electronic configuration, usually resembling the electron structure of noble gases.
Answer for screen readers
Atoms gain, lose, or share electrons in order to attain a stable electronic configuration, usually resembling the electron structure of noble gases.
More Information
Atoms typically react to achieve a more stable low-energy state. For many elements, this stability is achieved by having a full outer electron shell akin to the configuration of noble gases, which are inert and stable.
Tips
A common mistake is to think atoms can lose or gain protons to achieve stability. Protons are part of the nucleus and require much higher energy to be removed, unlike electrons.
