A labeled periodic table of elements with names, will help you to know the different elements and understand their placement in the periodic table. Read on to know more about the periodic table and its elements...
A periodic table is nothing but a systematic arrangement of the chemical elements, in a table form. This credit for this invention goes to the Russian scientist named, Dmitri Mendeleev. Since its invention, the periodic table has undergone number of changes. The periodic table is considered one of the most important reference, in studies related to chemistry. It consists of all the chemical elements known till date.
Periodic Table of Elements
As discussed earlier, periodic table is a tabular arrangement of all the known chemical elements. The elements are arranged from left to right, with increasing atomic number. Atomic number and atomic mass are two major properties of any chemical element. The atomic number of an element is, the number of protons present in the nucleus of the atom of the respective element, while atomic mass is the summation of proton mass, electron mass and neutron mass of an atom of the respective element. The atomic number is unique for every element. The atomic symbol is the abbreviation of the chemical element in the form of one or two letters. Many of the atomic symbols are shortened Latin names of these chemical elements. Periods and groups are two important characteristics of the periodic table. The horizontal rows of the periodic table are referred as periods, while the vertical columns are referred as groups. Groups and periods are two most important methods of classifying the elements in the periodic table. The elements present in the periodic table are classified under different groups, depending on their chemical and physical properties. They are, metalloids, alkali metals, alkaline earth metals, transition metals, other elements, non-metals, halogens, noble gases and rare earth elements. In many of the groups, the member elements have similar properties. Let us understand about each of these periodic table elements' groups.
Metalloids: The elements that come under metalloids group, bear the properties of both metals and non-metals. Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium and Polonium are the elements that are known as Metalloids. These elements are placed in group 13, 14, 15 and 16.
Alkali Metals: Alkali metals are placed in the first group of the periodic table and consist of elements Lithium, Sodium, Potassium, Rubidium, Cesium, Francium. All these elements are highly reactive and do not occur freely in nature.
Alkaline Earth Metals: Alkaline earth metals are placed in the second group of the periodic table and are found in Earth's crust. Even these metals do not occur freely in nature. Beryllium, Magnesium Calcium, Strontium, Barium and Radium are the six, elements that belong to this category.
Transition Metals: All the elements that are placed in groups 3 to 12 are transition metals. Ductility, malleability and conductivity of electricity, are some of the basic properties of these elements. Chromium, Copper, Nickel, Mercury, Gold and Silver are some of the metals, that belong to this group.
Rare Earth Elements: Rare earth elements are located in the 3rd, 6th and 7th periods of the periodic table. Most of the elements that belong to this group are man- made or synthetic. Lanthanide and Actinide series together form the rare earth elements. Cerium, Curium, Europium, Uranium, etc are some of the rare earth elements.
Non-Metals: Hydrogen, Carbon, Nitrogen, Oxygen, Phosphorus, Sulfur and Selenium are seven non-metals located in the 14th, 15th and 16th group of the periodic table. These elements are very brittle and do not easily conduct electricity.
Noble Gases: Noble gases are located in 18th group of the periodic table. Helium, Neon, Argon, Krypton, Xenon and Radon are six noble gases, found in the periodic table.
Given below is a labeled periodic table of elements with their names and atomic number. Hold the mouse on each atomic symbol to know the name of the chemical element.
