📖 1. Chemical Bond Types

🔑 Key Concepts & Definitions

• Chemical Bond: An attractive force that holds atoms, ions, or molecules together in a chemical species, resulting from interactions between electrons and nuclei.

• Covalent Bond: A type of chemical bond formed by the mutual sharing of electron pairs between two atoms, typically nonmetals.

• Ionic (Electrovalent) Bond: A bond formed by the transfer of electrons from a metal to a non-metal, resulting in oppositely charged ions held together by electrostatic forces.

• Coordinate (Dative) Bond: A special covalent bond where both shared electrons originate from one atom, often seen in complex ions and molecules.

• Bond Polarity: The distribution of electrical charge across a bond, resulting in partial positive and negative charges; depends on differences in electronegativities of bonded atoms.

• Bond Length: The equilibrium distance between the nuclei of two bonded atoms; shorter bonds generally indicate stronger bonds.
