A chemical bone between atoms whereby incomplete electron orbits in the bonded atoms are satisfied by the two atoms sharing one electron. Some covalent compounds do display some ionic character, where the sharing is somewhat unequal (e.g. water) and th

the combination of two of more atoms by sharing of electrons. Covalent bonds are generally stronger than other bonds.

n: a method of forming compounds in which atoms share electrons, thus forming nonpolar, or covalent, unions.

n: the most common method of forming compounds, in which a positively charged ion and a negatively charged ion attract each other. Compare covalent reaction.

n: the quality of being either negative or positive;in magnetism. the north or south pole of a magnet.

n: in nature, molecule sconsist of group of atoms bonded together. Overall the electrial charge is zero beause the number of protons and electrons balance. However some covalent molecules may express polarity, where the electrical charges, though balanceing
