In an ionic bond, an electron leaves one atom to join another, while a covalent bond is a sharing of electrons between two atoms. Polar covalent bonds occur when two atoms share an uneven number of electrons. More »

Ionic compounds form when electrons transfer from one atom to another. Covalent compounds form when atoms share electrons, resulting in no net loss or gain of electrons as seen in ionic compounds. More »

In nonpolar covalent bonds, electrons are shared equally by both members of the bond, but they are shared unequally in polar covalent bonds. Polar covalent bonds occur when there is a difference in electronegativity, or ... More »

Carbon dioxide is a compound formed by the sharing of two pairs of electrons between each of the two atoms of oxygen and one atom of carbon. This leads to the formation of a double covalent bond between the atoms of oxyg... More »

A polar bond is a type of bond that is formed between two atoms that are sharing an electron, where one atom has a stronger attraction, or pull, on the electron than the other. A polar bond is a type of covalent bond, wh... More »

An ionic bond is a type of chemical bond established between two atoms by the transfer of the valence electrons from one atom to another. This type of bond is also known as electrovalent or polar bond. Salts are a good e... More »

An ionic bond forms between two ions of opposite charges. In ionic bonding, electrons transfer from one atom to another. The elements take on either a negative or positive charge. More »
