Examples. Two atoms of iodine (I) combine to form iodine (I 2) gas. One atom of carbon (C) combines with two atoms of oxygen (O) to form a double covalent bond in carbon dioxide (CO 2). Two atoms of hydrogen (H) combine with one atom of oxygen (O) to form a polar molecule of water (H 2 O).

Chemical bonding, any of the interactions that account for the association of atoms into molecules, ions, crystals, and other species. When atoms approach one another, their electrons interact and tend to distribute themselves in space so that the total energy is lower than it would be in any alternative arrangement.
Chemical bonds form when electrons can be simultaneously close to two or more nuclei, but beyond this, there is no simple, easily understood theory that would not only explain why atoms bind together to form molecules, but would also predict the three-dimensional structures of the resulting compounds as well as the energies and other properties ...
Chemical bonding is the general term used to describe the forces that hold atoms together in molecules and ions. Three idealized types of bonding are ionic bonding , in which positively and negatively charged ions are held together by electrostatic forces, covalent bonding , in which electron pairs are shared between atoms and metallic bonding ...
A chemical bond is an interaction that holds molecules and compounds together by the sharing or exchanging of electrons. When an atom comes into proximity to another atom and its valence (outer) electrons are attracted to the positive (nuclear) charge of the other atom, a bond between the two atoms can be formed.
Some examples are nitrogen gas (N 2), oxygen gas (O 2), and hydrogen gas (H 2). One way to figure out what type of bond a molecule has is by determining the difference of the electronegativity values of the molecules. If the difference is between 0.0-0.3, then the molecule has a non-polar bond.
chemical: A substance formed from two or more atoms that unite (bond) in a fixed proportion and structure. For example, water is a chemical made when two hydrogen atoms bond to one oxygen atom.
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
In chemistry, a bond or chemical bond is a link between atoms in molecules or compounds and between ions and molecules in crystals. A bond represents a lasting attraction between different atoms, molecules or ions.
