Types of bonds

ionic bonds

Ionic bond are those made up of metals and nonmetals an example would be sodium bromide.  Ionic bonds are formed when an atom is not found in the bond and one or more electrons are shared to make up for the lost atom. An example of this would be sodium bromine.


Covalent bonds

Covalent bonds are formed by two nonmetals where positive atoms of one element are attracted to the others negative electrons. This can be called an transferring bond because of the transfer of electrons to atoms. An example would be H2O or water, part hydrogen, part oxygen.


Metallic bonds

Metallic bonds are formed between two metals. They give more freedom to move around to their atoms which are inside crystals. An example would be copper.
