Chemical Bond: The force that holds atoms together in molecules or compounds, resulting from interactions between electrons and nuclei.
Ionic Bond: A type of chemical bond formed by the transfer of electrons from a metal to a non-metal, leading to the formation of oppositely charged ions (cations and anions) that attract each other.
Covalent Bond: A bond where atoms share one or more pairs of electrons to attain stability, which can be non-polar (equal sharing) or polar (unequal sharing).
Metallic Bond: A bond characterized by delocalized electrons shared among metal atoms, responsible for properties like electrical and thermal conductivity.
Hydrogen Bond: A weak attraction between a hydrogen atom attached to F, O, or N and another electronegative atom, crucial in water and biological molecules.
Octet Rule: The tendency of atoms to bond in a way that results in a full outer shell of 8 electrons, similar to noble gases.
