Each kind of atom makes up a pure substance called an element. You may have heard of oxygen, lead, and gold. Well, these are all examples of elements. Can you believe that a pure gold necklace is made up of billions of gold atoms?
the element 'oxygen' is part of the mixture 'air' and some of the properties of air are due to the oxygen part - but those properties are generally less strong / intense than those of pure oxygen because of the presence of the other constituents of the mixture called 'air', e.g. ...

An Atom and Subatomic Particles:An atom is regarded as the smallest particle of a chemical element that is existing in nature. All substances are made up of either neutral or ionized atoms. The atoms of all elements have three suba...
It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently ...
N Type Semiconductor Definition: An n-type semiconductor is defined as a type of semiconductor that has been doped with pentavalent impurities to increase its conductivity by adding free electrons. Doping Process: Doping involves adding impurities like antimony, arsenic, or phosphorus to a pure semico...
