Metals and Non-metals

Document Content and Description Below

Physical Properties of Metals and Non-Metals Do you know how many elements are there in our periodic table? There are 118 elements in the modern periodic table. These elements can be broadly classi... fied as metals and non-metals depending on their properties. Elements that lose electrons to form compounds are called metals whereas elements that gain electrons to form compounds are called non-metals. Elements such as Si, Ge, As, Sb and Te show the characteristic properties of both metals and non-metals. They are called semi-metals or metalloids. Here, we will discuss metals and non-metals along with their physical properties in detail. Metals These elements are electropositive and contain less than or equal to three electrons in their valence shell. Metals such as aluminium, copper, and iron are widely used around us. Metals are used for the construction of bridges, automobiles, airplanes, ships, trains, etc. We will now discuss the physical properties of metals [Show More]
