How are atoms in a molecule held together? through shared energy through shared protons through shared neutrons through shared electrons

Atoms in a molecule are primarily held together **through shared electrons**. This type of bonding is known as a **covalent bond**. In a covalent bond, atoms share one or more pairs of electrons to achieve a more stable electron configuration, typically resembling that of a noble gas. This sharing allows each atom to fill its outer electron shell, contributing to the molecule's stability. **Incorrect Options Explained:** - **Through shared energy:** While energy is involved in the formation of bonds, atoms are not held together by sharing energy itself. - **Through shared protons:** Protons reside in the nucleus of an atom and are not shared between atoms in a molecule. - **Through shared neutrons:** Neutrons are also located in the nucleus and do not play a direct role in holding atoms together in molecules. **Example:** In a water (H₂O) molecule, the oxygen atom shares electrons with two hydrogen atoms, forming covalent bonds that hold the molecule together. **Summary:** The correct way atoms in a molecule are held together is **through shared electrons**.
