7. What are the characteristics of a neutron?
1) It has no charge and no mass 3) It has a charge of +1 and no mass
2) It has no charge and a mass of 1 amu
4) It has a charge of +1 and a mass of 1 amu
8. An electron has a charge of
1) -1 and the same mass as a proton 3) -1 and a smaller mass than a proton
2) +1 and the same mass a proton 4) +1 and a smaller mass than a proton
9. Compared to an electron, a neutron has
1) The same mass and the same charge 3) A different mass but the same charge
2) The same mass but a different charge 4) A different mass and a different charge

10. Which are true of neutrons?
1) They have a mass of zero and are found outside the nucleus
2) They have a mass of zero and are found inside the nucleus
3) They have a mass 0f 1 amu and are found outside the nucleus
4) They have a mass of 1 amu and are found inside the nucleus
11. The mass of an atom is due primarily to the
1) Mass of protons plus the mass of electron
2) Mass of neutrons plus the mass of electron
3) Mass of protons plus the mass of positron
4) Mass of neutrons plus the mass of protons

12. Which is true of protons and neutrons?
1) They have approximately the same mass and the same charge
2) They have approximately the same mass but different charge
3) The have different mass and different charge
4) They have different mass but the same charge
13. Compared with an electron, a proton has
1) More mass and the same charge
2) More mass and an opposite charge
3) Equal mass and the same charge
4) Equal mass and an opposite charge
14. The mass of a proton is approximately
1) 1/2000 times the mass of a neutron and a unit positive charge
2) 1/2000 times the mass of a neutron and a unit negative charge
3) 2000 times the mass of an electron and a unit positive charge
4) 2000 times the mass of an electron and a unit negative charge
15. A student constructs a model for comparing the mass of subatomic particles. The student selected a
small metal sphere with a mass of 1 gram to represent an electron. A sphere with which mass
would be most appropriate to represent a proton?
1) 1 g 2) ½ g 3) ½ 000 g 4) 2000 g
