2. A 1 Question Said that matter is made of atoms which move through empty space

3. A 2 Question Stated that empty space cannot exist and that matter is made up of earth fire, and water

4. A 3 Question Marked the beginning of the modern atomic theory

5. A 4 Question Dalton’s idea’s were most like who??

6. B 1 Question Atoms are composed of extremely small particles called?

7. B 2 Question Atoms of a given element had identical what?

8. B 3 Question Atoms do this when they combine to make compounds

9. B 4 Question In a chemical reaction, atoms do this.

10. C 1 Question The smallest part particle of an element that retains the properties of the element.

11. C 2 Question Discovered by JJ Thomson, this atomic particle was found using a cathode ray tube

12. C 3 Question The model Thomson composed that states that the atom is a uniform, positively charged sphere containing electrons.

13. C 4 Question The scientist and name of the experiment who used the Plum Pudding model to determine properties of the nucleus, including charge, relative size, and density

14. D 1 Question Carries a positive charge and is located in the nucleus of the atom

15. D 2 Question Discovered by James Chadwick, contains a neutral charge, is located in the nucleus, is about the same mass as a proton

16. D 3 Question Carries a negative charge, located surrounding the nucleus, and has a mass much smaller than a proton and neutron

17. D 4 Question Most of the atoms’ mass

18. E 1 Question The number of protons in an atom is also the elements identity

19. E 2 Question Atoms with the same number of protons but different number of neutrons

20. E 3 Question The atomic number plus the number of neutrons

21. E 4 Question Defined as one twelfth the mass of a carbon-12 atom. (An easier way to express the mass of an atom

22. F 1 Question The rays and particles emitted by radioactive material

23. Question F 2 A reaction that involves a change in an atom’s nucleus.

24. F 3 Question Unstable nuclei lose energy by emitting radiation in this spontaneous process.

25. F 4 Question Substances that spontaneously emit radiation is called this process

26. G 1 Question Contains two protons and two neutrons and is equivalent to a Helium-4 nucleus

27. G 2 Question Consists of a fast moving electron

28. G 3 Question High energy radiation that possess no mass usually accompanies alpha and beta radiation

29. G 4 Question The quantities that are conserved when balancing a nuclear reaction
