In a nonpolar covalent bond, cA = cB2 and the electron pair is shared equally between the two atoms. 

The bond that holds two fluorine atoms together in an F2 molecule would be classified as nonpolar covalent because —... 

Considering that the charge on oxygen is very approximately —1, it would seem that we have to conclude that structure 2 is the best representation of this bond. This structure implies that the C=0 bond consists of two very different bonds—a nonpolar covalent bond represented by the bond line and a fully ionic bond represented by the two charges. How-... 

The indicated bond in butane is a nonpolar covalent single bond between two carbon atoms. 

A halogen molecule contains one nonpolar covalent single bond, as shown by its Lewis structure. As we descend the 7A family from F2 to I2, the size of a halogen atom increases and so the bond length increases. The strength of the X-X bond varies it increases from F2 to Cl2, then decreases from Cl2 to Br2 to I2. 

Most chemical bonds are neither totally covalent nor totally ionic. As the difference in electronegativities between the two atoms increases, chemical bonds change from nonpolar covalent to polar covalent and then to ionic as the polarity of the bond increases. 

How many polar and nonpolar covalent bonds are there between the atoms in the ethene molecule C2H4 ... 

If the electrons are shared equally, the bond is a nonpolar covalent bond, but unequal sharing results in a polar covalent bond. 

Covalent bond A chemical bond in which the bonding electrons are shared between the bonded atoms. If the sharing is equal, the bond is termed nonpolar covalent. If one atom is more electronegative, the electrons are not equally shared. See Polar covalent bond. 

Lewis s model established the idea of the nonpolar covalent bond, although his idea of the cubic arrangement of electrons had several major flaws, for example, how to represent a triple bond in which six elec-...

The relative tendency of a bonded atom in a molecule to attract electrons is expressed by the term electronegativity. The higher the electronegativity, the more effectively does the atom attract and hold electrons. A bond formed by atoms of dissimilar electronegativities is called polar. A nonpolar covalent bond exists between atoms having a very small or zero difference in electronegativity. A few relative electronegativities are... 

Polarity is a physical property of a compound, which relates other physical properties, e.g. melting and boiling points, solubility and intermolecular interactions between molecules. Generally, there is a direct correlation between the polarity of a molecule and the number and types of polar or nonpolar covalent bond that are present. In a few cases, a molecule having polar bonds, but in a symmetrical arrangement, may give rise to a nonpolar molecule, e.g. carbon dioxide (CO2). 

The term bond polarity is used to describe the sharing of electrons between atoms. In a nonpolar covalent bond, the electrons are shared equally between two atoms. A polar covalent bond is one in which one... 

In general, if the electronegativity difference is equal to or less than 0.5 the bond is nonpolar covalent, and if the electronegativity difference between bonded atoms is 0.5-1.9 the bond is polar covalent. If the difference in electronegativities between the two atoms is 2.0 or greater, the bond is ionic. Some examples are shown below.
