Chemical change
Atoms that chemically combine form a molecule.
This property is called reactivity.

Chemical change
This chemical property is called reactivity.
They form new chemical bondings, loss or gain electrons.
Substances that combine or change to form new substances go through a chemical reaction. In a chemical reaction, bonds between atoms are broken and new bonds are formed. This results in the creation of new substances with different properties than the original substances.
This is called reactivity.
