When none of the elements in acompoundis a metal, no atoms in the compound have anionization energylow enough for electron loss to be likely. In such a case, covalence prevails. As a general rule,covalent bondsare formed between elements lying toward the right in theperiodic table(i.e.,...
Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. FromScience News This behavior indicated that the hydrogen atom was shared between the two fluorine atoms equally, rather than being closely bound to one fluorine atom by a covalent bond and more loosely bound ...
Covalent bonds are formed by equal sharing of electrons. Understand Covalent Bonding with Properties, Types - Polar, Non-Polar bonds, Difference between Covalent and Ionic Bonds, Examples
Coordinate covalent bonds can form in simple diatomic molecules and highly complex coordination complexes. As long as a lone pair of electrons is donated from a single atom to form the bond, the bond is classified as a coordinate covalent bond. Molecules containing coordinate covalent bonds may ha...
(green). The attractive forces are equal in magnitude, but opposite in sign. Each hydrogen nucleus attracts both electrons. The net result is that the energy of the system decreases when the bond forms. This simple electrostatic model for bonding does not adequately describe chemical bonds. For...

scientists don't make things to bug themselves. There're practical reasons to make such definition. The properties of covalent bonds and "ionic bonds" could be very different that we need to distinguish them and discuss separately. (Without considering the borderline cases ) such ...
A bond length that is shorter than the sum of the covalent radii of the bonded atoms, however, does not necessarily imply the presence of formal multiple bonds. It has been known for many years that bonds between atoms of different electronegativities (i.e., bonds with partial ionic ...
