Answer the questions below.
1. What are the building blocks of matter? Atoms
2. What are the two main parts of an atom? Nucleus and electron cloud
3. Name the subatomic particles and describe the charges.
a. Protons- positive
b. Nuetrons- nuetral
c. Electrons- negative
4. What is the atomic number of aluminum? 13
What does the atomic number mean? There are 13 protons in Aluminum. The atomic number
tells the number of protons
[A.P.E (atomic number= protons=electrons)]
5. What is the mass number of aluminum? 27 (round the number to a whole number)
What does the mass number tell us? The total number of protons and nuetrons in the atom
[M.A.N (mass number= atomic number (protons) + nuetrons)]

periodic table). Si and Ge (Answers may vary, if you look at mine I attached they are in purple)
15. Oxygen has an atomic number of 8. Name an element that you would expect to be most similar
to oxygen in terms of its chemical properties (same number of valance electrons, if you look on
periodic table you will see 1A (1 valance electron), 2A (2 valance electrons), 3A (3 valance
electrons) and so on). Se, S, Te, Po
16. Lithium, atomic number 3 will most likely react which of the following elements? (Lithium has 1
valance electron and Chlorine has 7, remember the magic number to react is 8)
a. Sodium (Na) because it is in the same column.
b. Argon (Ar) because it is a noble gas.
c. Chlorine (Cl), because it is a nonmetal.
d. Calcium (Ca, because it is in the same row.

25. Describe the relationship between mass and weight. Mass is the amount of matter in an object
and weight the effect of gravity on an object
26. Explain Newton’s first law.
An object in motion will stay in motion unless acted upon by another force just as an object at
rest will stay at rest unless acted on by another force.
27. Explain Newton’s second law.
If you increase the force, the acceleration increases yet if you increase the mass, the
acceleration decreases.
28. Explain Newton’s third law.
For every force, there is a reaction force of equal strength in opposite directions.
Label each of the forces as balanced or unbalanced. Then list the net force of each one.
1. 1200- 800 = 400 N, Up/Unbalanced
2. 800-600 = 200 N, Down/Unbalanced
3. 50-50 = 0
20-0 = 20
20 N, Left/Unbalanced
4. 3-3 = 0
5-5 = 0
0 N, Balanced
5. 40-25 = 15 N, Up/Unbalanced
