It is based on the number ten, used around the world, and convenient/easy for scientists to share information.
12. What are the differences between atoms and molecules?
Smallest unit of matter; made of protons, neutrons, and electrons; has a nucleus surrounded by shells/orbits
Made of 2 or more atoms; atoms can be the same or different
13. Draw what the four states of matter look like.
14. What are some examples of plasma?

17. Define the following phase changes of matter:
Gas à Liquid
Solid à Liquid
Liquid à Solid
Liquid à Gas
18. Describe the following parts of an atom:
Large, positively charged, found in the nucleus, determined by the atomic number
Large, no charge, found in the nucleus, determined by subtracting atomic number from the atomic mass
Small, negative charge, found in the shells/orbits, determined by finding the number of protons
19. Describe the following terms:
The sum of the Protons and Neutrons of an element
The number of Protons found in an atom/element
The abbreviation for elements on the periodic table; can be one – two letters
20. Describe what is happening in the graph below at points A-E.
Matter is a solid; temperature is increasing
Temperature is constant; solid is melting
Matter is a liquid; temperature is increasing
Temperature is constant; liquid is evaporating
Matter is a gas; temperature is increasing
21. What must be added to get from A to E?
Thermal (heat) energy to increase temperature and separate particles.
22. Draw and label an atom (Bohr model) for the element Neon (Ne).
