String theory is the idea in theoretical physics that reality is made up of infinitesimal vibrating strings, smaller than atoms, electrons or quarks. According to this theory, as the strings vibrate, twist and fold, they produce effects in many, tiny dimensions that humans interpret as everything...
defines the type of atom, i.e. which element it is an atom of. As indicated in theList of Chemical Elements, each atomic number corresponds to one single specific element. What about the number of neutrons in atoms ? Some elements have atoms that can include more than one number of neut...
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw ...
Atoms have great variations in weight, although they are all about the same size. The diameter of an atom is a million times smaller than one strand of thick human hair, very tiny indeed. The diameters of atoms range from approximately 0.1 to 0.5 nanometers. For example, plutonium, which ...
An atom can be an ion, but not all ions are atoms. These are the important differences between an atom and an ion.
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Modularity means your program is built like the universe. The world is made of molecules, which are made of atoms, electrons, nucleons, quarks, and (if you believe in them) strings. Likewise, good programs erect large systems from smaller ones, which are built from even smaller building blo...
The mass of any substance is the amount of matter present in it. By matter, it can be atoms, ions, or molecules. Every substance is made up of matter and hence possesses a mass. In the case of atoms, it has protons,...

Democritus 460 BC - Greek philosopher proposes the existence of the atom He pounded materials until he made them into smaller and smaller parts He called them atoma which is Greek for “indivisible”. Democritus His Theory: All atoms: Are small hard particles Are made of a single material form...
