What is the periodic table of elements? The periodic table is a tabular display of chemical elements organized on the basis of their atomic numbers. It is widely used in chemistry, physics and related sciences to show the relationship between groups of chemicals. Research and then play this game on the periodic table to practice.
The Periodic Table of Elements Explained
What is the Periodic Table of Elements? The periodic table was first devised in the 19th century by Mendeleev and Newlands. This article explains the history of the periodic table, as well as a brief explanation of the elements in a cell phone.
Mendeleev's periodic table
Although he is best known for developing the periodic law, Mendeleev is also credited with developing the periodic table of elements. Although he was not the first to discover elements, his work helped to determine the properties of many other substances. This table has been used in numerous fields and applications since it was published in 1869. However, it's not entirely clear how he came up with it.
Newlands's table of elements
Newlands's periodic table of elements arranged the elements in increasing atomic masses and began with hydrogen and ended with thorium. In the process of putting together the periodic table, Newlands compared the properties of the different elements to the octaves of music. As a result, his table is also known as the Newlands's law of octaves. The eighth element is sodium, and it is also known as the lithium-sodium-iodine-sodium group.
De Chancourtois's table of elements
The periodic table of elements is an order of chemical elements, showing how all elements have similar properties that are related to each other. The concept of periodicity was introduced by French geologist Alexandre-Emile Beguyer de Chancourtois. He constructed a cylinder with sixteen turns, lining up similarly-shaped elements. The periodicity of chemical elements was then observed to be a periodic function of their atomic weights.
The Periodic Table of Elements includes fifteen elements called actinides. This group of elements consists of actinium, uranium, thorium, and protactinium. Each of these elements is radioactive. In addition to actinium, actinides are also found in the periodic table as a group called lanthanides. They have similar properties and are commonly included with actinides.
