A labeled periodic table is one of the most preferred and used materials for people in the science and medicine field. In here, the elements are systematically arranged, typically from the left to the right. The arrangement is according the elements’ atomic number.
This table also has two rows, the horizontal, which contains the periods, and the vertical that shows the groups. These two rows show how different each element are based on their physical and chemical characteristics. For this article the groups will be discussed while the next entry will talk about the periods
Labeled Periodic Table: The Groups
Elements under this have the properties of metals and non-metals. They belong to the group 13 to 16. Among the elements that fall under this are Boron, Germanium, Antimony, Arsenic, Polonium and Tellurium.
* Alkali Metals
They are in the 1st group in the labeled periodic table. Under this are reactive elements such as Lithium, Potassium, Cesium, Sodium, Rubidium, and Francium.
* Alkaline Earth Metals
Elements that fall to this are those that are found in the Earth’s crust. They are placed within the second group.
* Transition Metals
Ductile, malleable, conductor of electricity are the words that describe the elements under this category. Chromium, Nickel, Copper, Mercury, Silver and Gold are considered transition metals. They are under the groups 3 to 12.
* Rare Earth Elements
They are found in the third, sixth, and seventh periods. Examples of this are Cerium, Curium, Europium, and Uranium.
These brittle elements belong to the fourteenth to sixteenth group. Hydrogen, Carbon, Nitrogen, Phosphorus, Selenium and Sulfur are considered non-metals.
* Noble Gases
Elements under this are located in the eighteenth group. The noble gases are Helium, Argon, Neon, Krypton, Radon and Xenon.
If you are someone who is in the scientific field, you must consider this table as one of your closest buddies. Sure, a labeled periodic table looks confusing, but taking time to understand how it is used will surely clear out all your questions.
