Let's talk about the three different bonds that elements can have. Elements can share an Ionic, Covalent, or Metallic bond with an other atom. The dictionary definition of Chemical Bonds is as follows. "A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms."
First lets talk about Ionic bonds. It is important to know that perfect Ionic bonding (when one atom steals an electron from another) cannot exist. All ionic compounds have some degree of covalent bonding, or electron sharing. So, the term "Ionic bonding" is given when the Ionic percentage is greater than the covalent percentage (that is, a bond in which a large electronegativity difference exists between the two atoms), causing the bonding to be more polar (Ionic) than in covalent bonding where electrons are shared more equally.

Next lets talk about Covalent Bonds. A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The stable balanced forces between atoms when they share electrons is known as covalent bonding.For many molecules, the sharing of electrons allows each atom to obtain the noble gas configuration, corresponding to a stable electronic configuration.

Finally lets talk about metallic bonds. Metallic bonding happens because of electromagnetism and shows forces that occurs between conduction electrons (in the form of an electron cloud of delocalized electrons) and positively charged metal ions. Metallic bonds are what metals are made up of such as Gold or Silver. Some easily identifiable characteristics of metallic bonds are the fact that they are shiny and conductive.
