Atoms are tiny particles that comprise the whole universe. These tiny atoms have enormous amount of energy. Atoms are the tiniest particles into which a substance can be divided without changing into something else.
Atoms actually consist of open spaces in which tiny particles orbit move around the nucleus. These particles travel so fast that they look like solid. The smallest particle of a substance contain about one million billion atoms and these can be seen individually under very powerful electron microscopes.
Below Atoms info from Wikipedia (Read More):-
The atom is a basic unit of matter consisting of a dense, central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except in the case of hydrogen-1, which is the only stable nuclide with no neutron). The electrons of an atom are bound to the nucleus by the electromagnetic force. Likewise, a group of atoms can remain bound to each other, forming a molecule. An atom containing an equal number of protons and electrons is electrically neutral, otherwise it has a positive or negative charge and is an ion. An atom is classified according to the number of protons and neutrons in its nucleus: the number of protons determines the chemical element, and the number of neutrons determine the isotope of the element.
