Today on Chemistry the main topic we discussed was the atom. The atom has three main pieces that contribute to the entire structure of the atom. There are three pieces within an atom including the proton, neutron and the electron. A proton is located in the nucleus or the center of the atom with positive charge. A neutron, also located in the nucleus, has no charge. Electrons are the third contributing factors with in an atom. They move around the nucleus in a circular direction in the electron cloud and have a negative charge. Electrons behave like light by moving in waves, and have a little bit more mass than a photon. When examining the Iron (Fe) atom, all atoms are made up of spheres that are filled with “heavy” light. It should be noted that the radius of the atom is a thousand times greater than the radius of the nucleus.
