Periodic table

The periodic table is made up of elements, and has 7 periods, and 18 groups. It is arranged by the number 0f protons in its nucleus, in ascending order. If the number of electrons in the element's valence shell is stable, it will not react so easily. Also, for groups 0, and groups 7, they react easily, because they are one electron less of being stable.

Relations with chemistry

For example, Hydrogen which has 1 electron, is able to react easily with the element chlorine, which is lacking 1 electron to being stable, will result in an ionic reaction. The one proton from Hydrogen will be shared with the chlorine element, and one from the chlorine will be shared and Hydrogen would have 2 electrons in its valence shell, and the Chlorine would have 8 electrons in the valence shell of it.

The types of reactions:

Ionic reaction (organic with metal)

Organic reaction (organic with organic)

Metallic reaction (metal with metal)
