Chemical bonding is the attraction between atoms that allows the formation of chemical substances that contain 2 or more atom.

I learned in this lesson that dangerous elements can be made useful such like the Sodium and Chlorine,these elements are dangerous but when they react they form a very useful substance such as salt.Table salt is an ionic compounds since it has a metal element Sodium and a non-metal element Chlorine.I also learned that chemical bonding is the responsible for the formation of a new chemical substance.

Ionic Bond
    - is formed through an electrostatic attraction between two oppositely charged ions
    - the transfer of electron from metal to non-metal
    - one common example is Table salt (NaCl)
