What is an atom? Explain. What is Matter? Anything that has mass and takes up space is considered to be matter. It is made up of atoms and molecules, which interact with one another through a variety of interactions to form the physical elements that constitute our universe. ...

the total mass of the protons, neutrons, and electrons in a single atom when it is at rest. This is not to be associated or mistaken for atomic weight. Atomic mass is measured by mass spectrometry. You can figure the molecular mass of an compound by adding the atomic mass of its atoms...
Today, atomic research is focused on studying the structure and the function of matter at the subatomic level. This not only consists of identifying all the subatomic particles that are thought to make up an atom, but investigating the forces that govern them. These include strong nuclear forces...
John Dalton in 1803, proposed a modern theory of the atom based on the following assumptions: matter is made up of atoms that are indivisible and indestructible; all atoms of an element are identical; atoms of different elements have different weights and different chemical properties; atoms of ...
