The Basic Building Blocks of Everything Modern Science had helped us to know that Everything that exists are made of simple basic building blocks called Atoms.  Many atoms combine to form Molecules.  Atoms with similar structure and properties are said to be belong to certain type of Element.  Through this article I going to explain what is an atom , a molecule and an element. What is an atom? The term 'atom' comes from the Greek word 'atomos', meaning 'indivisible'.  Earlier, it was considered that atoms were the smallest unit of a substance and could not be split further.  Today,we know that atoms can be further split into smaller particles.  An atom is made up of the atomic nucleus, which consists of positively charged protons and an equal number of neutrons, and atomic shells.  These are occupied by negatively charged electrons, which move at high speeds around the atomic nucleus-like planets around the sun.
