The Groups of the Periodic Table

The Periodic Table has a classification, according to the properties of the elements they are organizing by groups. 

Let's learn some characteristics of each group:


1. Alkali Metals:

Group 1

—Hydrogen is not a member, it is a non-metal

—1 electron in the outer shell

—Soft and silvery metals

—Very reactive  with water

—Conduct electricity

   

2. Alkaline Earth Metals:

Group 2

—2 electrons in the outer shell

—White and malleable

—Reactive, but less than Alkali metals

—Conduct electricity

3. Boron Family:

Group 3 0r 13

—3 electrons in the outer shell

—Most are metals

—Boron is a metalloid

4. Carbon Family:

Group 4 or 14

—4 electrons in the outer shell

—Contains metals, metalloids, and a non-metal Carbon (C)

5. Nitrogen Family:

Group 5 or 15

—5 electrons in the outer shell

—Can share electrons to form compounds

—Contains metals, metalloids, and non-metals

6. Oxygen Family:

Group 6 or 16

—6 electrons in the outer shell

—Contains metals, metalloids, and non-metals

—Reactive

7. Halogens:

Group 7 or  17

—7 electrons in the outer shell

—All are non-metals

—Very reactive are often bonded with elements from Group 1

8. Noble gases:

Group 8 or 18

—Exist as gases

—Non-metals

—8 electrons in the outer shell = Full

—Helium (He) has only 2 electrons in the outer shell = Full

—Not reactive with other elements

Group of Transition metals and Group of Rare earth 

Groups in the middle

—Good conductors of heat and electricity.

—Some are used for jewelry.

—The transition metals are able to put up to 32 electrons in their second to last shell.

—Can bond with many elements in a variety of shapes.

The last two rows are the Rare earth metals the first is called Lanthanides and the second is called Antinides.

Some are Radioactive

—The rare earths are silver, silvery-white, or gray metals.

—Conduct electricity.
