Quarks and more.. What forces hold the atom together?

Quarks and more.. What forces hold the atom together?. Electromagnetic likes repel, opposites attract (+ or -). Strong Force interacts with hadrons or nucleons so the protons and neutrons binds them together works only at distances smaller than 1 quadrillionth of a meter!!!.

  1. Quarks and more..What forces hold the atom together? Electromagnetic likes repel, opposites attract (+ or -) Strong Force interacts with hadrons or nucleons so the protons and neutrons binds them together works only at distances smaller than 1 quadrillionth of a meter!!! Weak Force works with quarks and leptons and decides how flavors change helps stabilize nuclei through beta decay shorter distances than the strong force! Gravity Since this binds matter together based on mass, we think this plays no role in atoms

  2. What is a quark, anyway? fundamental particle which possess electric charge and 'strong' charge. Two categories: Hadrons and Leptons Hadrons- (strong force) combine in groups of two or three to form mesonsandbaryons Leptons- (weak force) include electrons, electron neutrino, tau, muon, moun neutrino, and tau neutrino

  3. So subatomic particles are themselves made of smaller particles! • Subatomic particles composed of fast moving points of energy called quarks Quark Calculationsfor protons and neutrons- Hadrons (strong force) Each proton is 2 up quarks and 1 down quark 2(2/3) – 1(1/3) = 4/3 – 1/3 = 3/3 or +1 Each neutron is 2 down quarks and 1 up quark 2(-1/3) + 2/3 = 0 Each electron is composed of leptons (weak force)

  4. There are several kinds of quarks quarks come in six different species (physicists call them 'flavors') each flavor has a unique mass.

  5. So, are there other characteristics of quarks? The two lightest are 'up' and 'down' quarks They combine to form protons and neutrons. The heavier quarks aren't found in nature and have so far only been observed in particle accelerators.
