In general, elements with small number of electrons in the outermost shell are metals (Group I and II). One common example is Silicon, which is widely used in semi-conductor industry. Metalloids are special, because they have the properties of both metals and non-metals. The elements include- boron, silicon, germanium, arsenic, antimony, tellurium and polonium. In the Periodic Table shown in this video, the metalloids are coloured orange. The elements that are near this line are called metalloids. Metals are on the left, while non-metals are on the right of the diagonal line. We can draw a diagonal line in the Periodic Table to divide the metals from non-metals. The elements in a Periodic Table can be classified based on their metallic and non-metallic properties. Metallic to non-metallic character of elements across a period The block of metals in the middle of Periodic Table, between Group II and III, are called transition elements, or transition metals. Group 0 is sometimes known as Group VIII.Ī Period is a horizontal row of elements. There are eight groups of elements, numbered in roman numeral, I, II, III, IV, V, VI, VII, 0. Elements are divided into Periods and Groups.Ī group is a vertical column of elements. The Periodic Table is a list of elements, arranged in order of increasing proton or atomic number. In this video, we will explore more on the Periodic Table, and find out what are the general features and patterns in the Periodic Table. Chemistry Online Learning Video – The Periodic Table
