A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding
Covalent compounds are substances formed by the sharing of electrons between atoms. In these compounds, atoms come together to achieve a stable electron configuration by sharing one or more pairs of electrons. This sharing of electrons creates covalent bonds, which are strong forces that hold the atoms together within the molecule.
Key characteristics of covalent compounds include:
1. **Electron Sharing:** Atoms in covalent compounds share electrons to attain a more stable electron configuration, usually resembling the noble gas configuration.
2. **Low Melting and Boiling Points:** Generally, covalent compounds have lower melting and boiling points compared to ionic compounds. This is because covalent bonds are typically weaker than ionic bonds.
3. **Non-Conductivity:** Covalent compounds are typically poor conductors of electricity in their pure state because they do not have free-moving ions. However, some covalent compounds can conduct electricity when dissolved in water or in a molten state.
4. **Molecular Structures:** Covalent compounds can exist as molecules with distinct structures. These structures can be simple, such as diatomic molecules (e.g., oxygen, O2), or complex, like large organic molecules.
Examples of covalent compounds include water (H2O), methane (CH4), carbon dioxide (CO2), and ammonia (NH3).
