We now know quite a bit about the interior of the atom, the fundamental building block of nature. There are just a few basic "parts" of an atom, and while it would be difficult for the average person to actually "see" and identify these parts on some specific atom, for example, a c...
The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10-31kg and a size too small to be measured by current techniques. Protons have a mass that is 1,...
