4. - No definite shape - Has definite volume

7. The particles of solids are held together by strong forces.

8. Since the particles are closer to one another, the attraction between particles is stronger than those in gases.

9. They move freely because they are far apart and there is negligible attraction between them.

11. - Light - Heat - Sound - Other forms of energy

12. Lowest compressibility of a solid is due to the closeness of the particles.

14. The particles are packed closely together in fixed positions.

16. The particles are closer to one another, nudging one another as they move.

18. Gases take the shape of the container because the particles are able to move freely to all parts of the container.

30. Charge Mass Electron -1 9.109 x 10^-29 Lightest Proton +1 1.672 x 10^-24 Almost same size and mass Neutron 0 1.675 x 10^-24

31. Proton and Electron are attracted to one another.

32. Proton – positively-charged particle (+)

33. Electron – negatively- charged particle (-)

34. J. J. Thompson – proposed the plum pudding model

36. P100 WT-FAX 100 Wed 24 Oct 14.09.4 RULE #1 The number of protons in a neutral atom is equal to the atomic number.

37. P100 WT-FAX 100 Wed 24 Oct 14.09.4 RULE #2 The number of electrons in a neutral atom is equal to the number of protons.

38. P100 WT-FAX 100 Wed 24 Oct 14.09.4 RULE #3 The atomic mass is equal to the sum of the number of protons and neutrons.

39. P100 WT-FAX 100 Wed 24 Oct 14.09.4 RULE #4 The number of neutrons is equal to the difference between the atomic mass and protons.
