What Is an Atom?

An atom is the smallest, but the most important part of everything that exists. In a one-half inch cube of any material there are about one hundred thousand billion billion of them! It is the "building block" of the Creator, the material of which all things are made. Einstein, the famous scientist, claimed that if the atomic energy in one-half pound of any substance were released it would equal seven million tons of TNT.
Researchers cannot understand how the atom, which is made up of protons, neutrons and electrons, is held together. They think it is like a magnet with positive and negative forces. However, when two common magnets are placed end to end they either attract each other or push each other apart (according to how the positive and negative ends are placed). Inside an atom this does not happen. Its parts are held together, but kept separate at the same time, with space between each one of them.
An object which appears to have no movement in it actually is composed of many billions of atoms whirling around their nucleus (center) millions of times each second, yet never flying away or ever touching one another. Here is a further reminder that "God... doeth great things and unsearchable; marvelous things without number." Job 5:8,98I would seek unto God, and unto God would I commit my cause: 9Which doeth great things and unsearchable; marvellous things without number: (Job 5:8‑9).
These are the smallest parts of a combined chemical substance containing a combination of atoms. Everything in the world is formed by various combinations of atoms. For instance, water is often referred to as H20. This simply means that two atoms of hydrogen are joined with one atom of oxygen to form a molecule of water. Incidentally, molecules are so small that a teaspoon of water holds as many molecules as there are teaspoonfuls of water in the Atlantic Ocean. Or, put another way, if the molecules in one drop of water were changed to grains of sand, this amount of sand could be used to make a concrete highway across the United States.
Atoms never change, but molecules can. Molecules in any substance vibrate rapidly when heated. If the heat increases enough the solid will change to liquid (even metal will do this) or become a gas (as wood does when it is burned), and the molecular structure changes.
An honest scientist must admit that there is a divine power who made these tiny but powerful elements and also controls them. The atom proves that the theories of evolution are wrong, because from its unchangeable character all matter is composed and cannot "evolve" into something else.
Scripture tells us, "The invisible things of Him from the creation of the world are clearly seen, being understood by the things that are made, even His eternal power and Godhead...." Rom. 1:2020For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: (Romans 1:20). Do you know Him as your God and His Son as your Savior?
