viz., elements, compound, and mixture. Elements are the purest forms of the matter among these three forms and again fall into three categories; metals, non-metals and metalloids. These three elements are bifurcated on the basis of their physical and chemical properties. ...
The number of well-known elements up till now is 118 elements, These elements can be classified according to their properties and electronic structure into
Every material in our environment is made up of elements. We know of \(118\) elements, \(94\) of which occur naturally and the remaining \(24\) of which are synthetic. These elements are classed as metals, nonmetals, and metalloids based on their physical and chemical properties. In th...
We know that metals are hard, ductile, malleable, good conductors of heat and electricity and have lustre. But some metals appear dull due to the formation of an oxide layer on their surface. Metals and non-metals exhibit several chemical properties. Thechemical properties of metalsdiffer from ...
To differentiate between metals and non-metals with respect to their chemical properties, we can consider the following points:1. Reactivity with Oxygen: - Metals: Metals react with oxygen to form basic oxid
Metals and Nonmetals Chemistry Questions with Solutions Q1: Give the physical and chemical properties of metals and non-metals. Answer: The following are some of the physical properties of metals: Nature is lustrous (shiny). Metal is an excellent heat and electrical conductor. The melting point ...
and Metalloids Metals, Nonmetals and Metalloids • The individual atomic properties of atoms can be related to the observed macroscopic behavior of the elements. The trends we observe across the periodic table help explain chemical behavior. ...
Physical Material Properties of Non Metals The physical properties of non – metals are : The solid non-metals are brittle or dull and soft as they can be broken down into a powdery substance or mass on tapping down with the hammer. Few examples are Coal and Sulphur. However, Diamond is ...
