Atoms last a long time, in most cases forever. They can change and undergo chemical reactions, sharing electrons with other atoms. But the nucleus is very hard to split, meaning most atoms are around for a long time. Structure of the Atom At the center of the atom is the nucleus. The nucleus is made up of the protons and neutrons. Super-tiny subatomic particles are used to create the parts of atoms. Protons, neutrons, and electrons can then organize to form atoms. Atoms are then used to create the molecules around us. As we just learned, there are almost 120 elements that can be found in the molecules we know. Smaller molecules can work together and build macromolecules ...

- Thus, atoms determine the composition of matter, and compounds can be broken down into their individual elements. The first estimates for the sizes of atoms and the number of atoms per unit volume where made by Joesph Loschmidt in 1865. |
- The knowledge about atoms does form the basis for further concepts in chemistry. Just like bricks form a variety of structures, atoms lead to the formation of molecules and compounds that are part of matter around us. Let us try to get a fair idea about the different formations of atoms. |

- Intermolecular Forces – Intermolecular forces are forces that act between stable molecules or between groups of macromolecules (molecules that contains many atoms). Intermolecular forces are different from intramolecular forces (ionic, covalent, and metallic bonds), which act to bind the atoms within a single particle.
Molecules and compounds. Compounds can be classified as ionic or covalent. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element.

- Sha512 collision probabilityA mass spectrometer is a device for separating atoms and molecules according to their mass. A substance is first heated in a vacuum and then ionized. The ions produced are accelerated through a magnetic field that separates ions of different masses. The graph below was produced when a certain element (element X) was analyzed in a mass spectrometer.
