| Video Discription | atoms are made of even tinier elements! We're pretty sure about quarks, but physicists are always looking for smaller, significant things... To create an element (like a mineral on your chart of elements...remember?) you assemble (or someone...or something does)...well. Here's an explanation: (a specific number of neutrons per element...) NEUTRONS (in the nucleus) (a neutron is a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen. Neutrons contain one up quark and two down quarks. The nucleus is held together by the "strong nuclear force," which is one of four fundamental fources (gravity and electromagnetism are two others). The strong force counteracts the tendency of the positively-charged protons to repel each other.) PROTONS (in the nucleus) (Protons are composed of two up quarks of charge + 23e and one down quark of charge − 13e. The rest masses of quarks contribute only about 1% of a proton's mass.) ELECTRONS=(An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron. Note: speed of electrons spinning: 2,200 kilometers per second (hydrogen) |
