Atoms lose, gain or share electrons in a chemical reaction in order to achieve a stable electron configuration. This is often referred to as the "octet rule," which states that atoms are most stable when their outermost electron shell is full, typically with eight electrons.

1. **Losing Electrons:** Some atoms, particularly those with one, two or three electrons in their outermost shell, may lose electrons to achieve a stable configuration. This is common in metals. When they lose electrons, they become positively charged ions, or cations.

2. **Gaining Electrons:** Atoms that have five, six or seven electrons in their outermost shell may gain electrons to reach a stable configuration. This is common in non-metals. When they gain electrons, they become negatively charged ions, or anions.

3. **Sharing Electrons:** Atoms can also achieve a stable configuration by sharing electrons with other atoms, forming what are known as covalent bonds. This is common in non-metal atoms when they bond together.

In summary, the reason why atoms lose, gain or share electrons in a chemical reaction is to achieve a stable electron configuration, which makes them more stable and less likely to react further.
