An orderly arrangement of all the known chemical elements according to their atomic number is known as the Periodic Table of Elements. All elements in the table are organized in a systematic order from left to right and top to bottom. The rows of the table are known as periods. All similar elements are grouped into columns. Each vertical column in the periodic table is called a group.
During early days, this table was used to calculate the chemical and physical properties of the elements. Today, the periodic table of elements is helpful for scientists and students as it can be used to calculate the chemical reactions that can occur in an element.
It was Dmitri Mendeleev, the Russian Chemist, who created the chart known as the Periodic Table of Elements in the year 1869. His discovery helped to organize all the elements that were discovered at that particular period of time. He successfully arranged the elements in the order of relative atomic mass. He also noticed that elements arranged in each column had same chemical properties. He predicted the discovery of many other elements in the future and therefore left space for these elements in his periodic table.
The periodic table of elements is one of the most useful tools in chemistry as it helps to identify which element has the same physical and chemical properties. All the elements are arranged in horizontal and vertical rows. The properties of these elements vary from one another as we move across the row.
With the help of a periodic table, you can easily identify the number of electrons and atomic mass of an element. The periodic table is one of the best reference tools and it also considered to be the masterpiece that displays chemical information in an organized manner.
Whether you are teaching a science class, helping students study or need the periodic table for any other reason, the Periodic Table of Elements (Circles) can help. This fully editable selection of PowerPoint slides will allow you to break down each group of elements into different parts to talk about them individually. The elements are shown as circles instead of being shown as usual squares which makes it easier for you to differentiate between the different ones. When you highlight one section, you will be able to isolate it among the others to make discussing it more simple.
