http://en.wikipedia.org/wiki/Atom

Most atoms are composed of three types of subatomic particles which govern their external properties:

electrons, which have a negative charge and are the least massive of the three;
protons, which have a positive charge and are about 1836 times more massive than electrons; and
neutrons, which have no charge and are about 1839 times more massive than electrons.

Quoted:
Virtually all elements heavier than hydrogen and helium were created through stellar nucleosynthesis and supernova nucleosynthesis. The solar system is thought to be formed of clouds of elements from many such supernovae, which date from more than 4.6 billion years ago. Most of the elements lighter than uranium (Z = 92) have either stable isotopes, or else radioisotopes long-lived enough to occur naturally on Earth. Two notable exceptions of light but short-lived radioactive elements are technetium Z = 43 (although some technetium has been found on Earth, this occurred only after the element was first synthesized artificially), and promethium Z = 61, which is found naturally only in stars where it was recently made. Several other short-lived heavy elements that do not occur on Earth have been found to be present in stars. Elements not normally found in nature have been artificially created by nuclear bombardment; as of 2006, elements have been created through atomic number 116 (given the temporary name ununhexium). These ultra-heavy elements are generally highly unstable and decay quickly.

Atoms that have lost or gained electrons to become electrically non-neutral, are called atomic ions. Ions are divided into cations with positive (+) electric charge; or anions with negative (−) charge.

The current view is that atoms are made up of protons and neutrons (which in turn are made up of quarks and gluons) and electrons. The protons and neutrons are at the central core called the nucleus, and the electrons revolve around it, being held in orbit by the electromagnetic force between the negatively charged electrons and the positively charged protons in the central nucleus. It is very much like the solar system with the sun at the center and the planets revolving around it. They were formed right after the "Big Bang" when our known universe originated from pure energy some billions of years ago. The energy was converted to the elementary particles (quarks, gluons, leptons etc...) from which protons and neutrons were formed. From these, atoms of different elements were produced.

The "matter is conserved" isnt properly stated. "Matter and energy are conserved" is a better way of saying it.

E=mc^2.

Energy is matter and matter is energy. The question you are asking is how to turn one into the other and back.

They make antimatter by putting a ton of energy in one space, and putting a magnetic field over that space so that charged flying particles are separated.

Virtual particle pairs are what I think you are talking about.

Matter cannot be created or destroyed. This is a fundamental law of physics. Everything you put into a reaction can always be accounted for.

Perhaps it would be helpful to meditate on atoms as being concepts of awareness/consciousness (sentience). Consider awareness/consciousness as the primal energy/substance which conceives and plays the universe within its self.

before everything, evolution is a theory and not actuality. the subject is that despite the fashionable theory is, it is not TOTTALY terrific suited. It desires to be corrected or more advantageous on. this scripture shows a symbolic expression helping evolution. the serpent or snake began with legs and replaced into cursed to circulate on this is abdomen. Genesis 3:14 14And our lord god mentioned unto the serpent, via fact thou hast completed this, thou paintings cursed particularly livestock, and above each and every beast of the sphere; upon thy abdomen shalt thou circulate, and airborne dirt and mud shalt thou consume each and all of the days of thy existence: Romans a million:20 For the invisible issues of him from the introduction of the international are patently seen, being understood via the failings that are made, even his eternal ability and Godhead; so as that they are without excuse:

Law of conservation of matter: Matter can neither be created nor destroyed.

atoms exist because protons and electron combine and make atoms

atoms cannot be created nor destroyed but can be split such as of uranium
