Microcosmology : Atom
to the modern science, the atom of a chemical element is rather a complicated system of smaller units such as protons, neutrons, electrons, etc. which are now called subatomic particles. The number of such subatomic particles has now crossed the figure 200.
It has been established beyond doubt that atoms of various chemical elements are very much similar to our solar system, with a number of negatively charged particles (electrons) rotating round the central nucleus in the form of standing waves, which itself
is composed of a number of positively charged particles (protons) and electrically neutral particles (neutrons). Protons and neutrons are much heavier than electrons so that the necleus contain 99.97% of the total atomic mass. The number of protons, neutrons, electrons are different in different elements but the atom on the whole is electrically neutral because the total change of all
