Play and Learn the Groups of the Periodic Table
Visit the next link to play and learn the groups of the elements of the Periodic table.
The History of the Periodic Table
Observe the next video to learn about the Periodic Table and its history; then take some notes about it on your notebook:
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:
3. Boron Family:
4. Carbon Family:
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.
