Length	Varies depending on the type of bond and atoms involved	Shorter than a single bond
Examples	Covalent bond, ionic bond, metallic bond	Double bond in ethene (C2H4)

Definition

A chemical bond is a force that holds atoms together in a molecule. It involves the sharing or transfer of electrons between atoms to achieve a stable electron configuration. Chemical bonds can be classified into different types such as ionic, covalent, and metallic bonds. On the other hand, a chemical double bond is a type of covalent bond where two pairs of electrons are shared between two atoms. This results in a stronger bond compared to a single covalent bond.

Formation

Chemical bonds are formed when atoms interact with each other through the sharing or transfer of electrons. In an ionic bond, one atom donates an electron to another atom, resulting in the formation of positively and negatively charged ions that are attracted to each other. In a covalent bond, atoms share electrons to achieve a stable electron configuration. On the other hand, a chemical double bond is formed when two atoms share two pairs of electrons, resulting in a stronger bond due to the increased electron density between the atoms.

Strength

Chemical bonds vary in strength depending on the type of bond and the atoms involved. Ionic bonds are relatively strong due to the attraction between oppositely charged ions, while covalent bonds are strong due to the sharing of electrons between atoms. Metallic bonds are also strong due to the delocalized electrons in a metal lattice. On the other hand, chemical double bonds are stronger than single covalent bonds due to the increased electron density between the atoms, which results in a more stable bond.

Flexibility

Chemical bonds can exhibit different degrees of flexibility depending on the type of bond. Ionic bonds are relatively rigid due to the strong attraction between ions of opposite charges. Covalent bonds can be flexible to some extent, allowing for rotation around the bond axis. Metallic bonds are also flexible due to the delocalized electrons in the metal lattice. On the other hand, chemical double bonds are less flexible compared to single covalent bonds due to the presence of two pairs of shared electrons, which restrict movement between the atoms.

Reactivity

Chemical bonds can influence the reactivity of a molecule by determining how easily it can undergo chemical reactions. Ionic bonds are relatively reactive, as the ions can easily interact with other ions to form new compounds. Covalent bonds can also be reactive, depending on the atoms involved and the strength of the bond. Metallic bonds are less reactive due to the delocalized nature of the electrons in the metal lattice. On the other hand, chemical double bonds can be more reactive compared to single covalent bonds, as the presence of two pairs of shared electrons can facilitate the breaking and formation of new bonds.

Applications

Chemical bonds play a crucial role in various applications in chemistry and materials science. Ionic bonds are commonly found in salts and other ionic compounds, which have diverse uses in industry and everyday life. Covalent bonds are prevalent in organic molecules and polymers, which are essential for the production of plastics, pharmaceuticals, and other materials. Metallic bonds are key to the properties of metals, such as conductivity and malleability. On the other hand, chemical double bonds are important in organic chemistry, particularly in the synthesis of complex molecules and the study of reaction mechanisms.
