Chapter 46 633 Section 46.8 Finding Patterns in the Particles Section 46.9 Quarks Section 46.10 Multicolored Quarks Section 46.11 The Standard Model P46.29 (a) The number of protons N p = × F H G I K J F H G I K J 1000 10 334 10 26 g 6.02 10 molecules 18.0 g protons molecule protons 23 . and there are N n = × F H G I K J F H G I K J 268 10 26 g 18.0 g 8 neutrons molecule neutrons 23 .. So there are for electric neutrality 26 . × electrons . The up quarks have number 2 3 34 10 2 68 10 9 36 10 26 26 26 . ×+ × ej up quarks and there are 2 2 68 10 3 34 10 8 70 10 26 26 26 . × down quarks . (b) Model yourself as 65 kg of water. Then you contain: 65 3 34 10 10 26 28 .~ × electrons 65 9 36 10 10 26 29 × up quarks 65 8 70 10 10 26 29 × down quarks . Only these fundamental particles form your body. You have no strangeness, charm, topness or bottomness.
