Atoms.
==The atoms have a nucleus which contains, two structures they are protons and neutrons. Protons are a solid subatomic particle that occurs in the nucleus of an atom. Neutrons are the the same as a protons but without any electrical charge. ==



==An atom is known as chemical matter. Atoms are the smallest element matter. An atom has small, closely packed, positively charged nucleus that is surrounded by sufficient negative electrons, that makes the entire atom electrically neutral. ==

==All atoms are the exact same size, the atomic diameter is approximately 2 × 10-8 centimeters. Atoms can’t be seen by just looking at them, they can’t even be seen with microscopes. An atom is the smallest piece of uncombined matter who's characteristics of the same matter but in larger proportions or retains the properties. When atoms are merged with each other they make the molecules of a chemical element, which is mostly referred to as a element. When different types of atoms are merged they form molecules of a chemical compound. ==



There have been more than 100 atoms recogized. Most of them are very rare. Approximately
== one dozen atoms are ordinary on Earth today’s time scientist have many different ways to study atoms. Scientist can figure out their size and weight. An atom is really small, if you make a tiny dot with your pencil that dot has over two million carbon atoms. The diameter of an atom does deffer much. The atoms were known to be invisible until the early 1900’s. ==
