Types Of Bonds by Bernardo De Alva
An Ionic Bond is where atoms will either loose or gain an electron. An excellent example would be NaCl(table salt). Having seven valence electrons, Cl will try to combine itself with another atom that has only one valence electron to achieve noble gas configuration, and in this case Na has to only one valence electron. Due to the octet rule, the valence electron from Na will move to complete Cl. Ionic Bonds tend to have solubility in water, not melt at a low temperature, and are only able to conduct in either a liquid state or dissolved in water.
A Covalent Bond is where the electron is shared between the atoms. An example would be O2. Covalent Bonds are also often soluble but they can melt at a lower temperatures.
A Metallic Bond is a balance between cations and anions. Most metals have this bond type and can conduct electricity. Usually they do not melt at low temperatures.
