They have formed a molecule, which is the name of a substance formed from the combination of atoms. This charged bond is known as an ionic bond.īy forming an ionic bond, the sodium and chlorine are not separate atoms anymore. The charged sodium and chlorine atoms become attracted to each other and form a bond. In ionic bond there is shift of electron from the donor to the acceptor. There exists 3 types of chemical bond and they are Ionic bond, covalent bond and hydrogen bonds and these are bound by electrostatic attraction.
As with magnets, positive and negative charges in atoms are attracted to each other. A bond which links atoms, molecules together is known as chemical bond. The chlorine atom now has more electrons, which have a negative charge, than protons, so it now has a negative charge. Ionic bonding is a form of chemical connection in which one atom loses valence electrons and gains them from another. Because protons have a positive charge, the sodium atom now has a positive charge. However, the sodium atom now has more protons than electrons. So, the chlorine atom will take the sodium’s electron and both atoms are happy. The chlorine atom has an outer shell with 7 electrons and only needs one more to fill its shell.

It can do this by taking electrons from the shells of other atoms or by giving away electrons until it loses its outermost shell and a full inner shell takes its place.įor example, the sodium atom has an outer shell with only 1 electron, which it wants to get rid of. Electron transfer produces negative ions called anions. However, atoms want to have an outermost shell that is completely full of electrons. Ionic bonds are formed between two or more atoms by the transfer of one or more electrons between atoms. Atoms are made of a nucleus (a core or center) that contains particles called protons and outer shells made of electrons.Īn atom always has an equal number of protons and electrons. Elements include substances like oxygen, nitrogen, and carbon. Ionic bonds are also known as electrovalent bonds.Įverything in the universe is made of atoms, the smallest possible form of an element. The purpose of cathodic protection (CP) systems is to prevent corrosion in metals. It is a loss of adhesion between a cathodic coating and its metal substrate due to a cathodic reduction reaction (corrosion reaction) taking place. An ionic bond is a chemical bond formed when one atom gives up one or more electrons to another atom. Disbonding is the failure of a coating to adhere to the substrate to which it was applied.
