2) We determine the element by the number of ______________ in the atom.
3) Which particle has a negative charge?
4) Fill out the following diagram for an atom with 7 protons:
5) What do the rings on the diagram above represent?
6) How many valence electrons does the atom in #4 have?
Station 2 – Periodic Table
7) Looking at the picture on the right, what is Lithium’s atomic mass?
8) How many neutrons does Lithium have?
9) What is the smallest element?
10) Why do the rows of the periodic table have 2, then 8, then 8, then 18
elements in them?
11) What is the atomic number the same as?
12) Which of the following elements is Lithium most similar to?
-Neon
-Beryllium
-Sodium
-Magnesium
13) (Bonus) Who was the scientist that first organized the periodic table?
Station 3 – Mass, Weight, Volume, and Density
14) If you went to Jupiter, a massive planet with high gravity, which of the following would change?
-Mass
-Weight
-Volume
-Density
15) Which of the terms above represents how much matter something has?
16) If an object is 15g and takes up 3mL of space what is its density?
17) Would the object in #15 float in water? Why? (Bonus: if you could change its volume, what would you have to
change it to so that it would be neutrally buoyant in water?)
18) If an object is 4 g/mL and takes up 2mL of space what is its mass?
19) Which would you predict to be more dense:
-Copper block
-Wood pencil
-Cloud
-Plastic cup
Station 4 – Phases of Matter
20) In which phase of matter do the particles have the most energy? (not counting plasma)
21) Which phase of matter is usually the densest?
22) What substance is an exception to the rule in #21?
23) Which phases of matter take the shape of their container?
24) What is the scientific term for describing how “sticky” a liquid is?
25) Which phase of matter takes up the whole container, regardless of size?
26) (Bonus): You are given a piece of coal for Christmas. You are quite unhappy about this, but when you ask the
person who gave it to you they say, “What are you so unhappy about? It’s the same element as a diamond!”
What is different between coal and diamond at the molecular level?
Station 5 – Phase Transitions
27) When you add enough energy to a solid to turn it into a liquid, what do we call this transition?
28) What is heat?
29) Which phase transition breaks the bonds between particles so they move freely?
30) Condensing is an (increase // decrease) in energy.
31) Write down the phase transition diagram we did in class, showing all three phases of matter and the four
transition names.
32) What is the name for the temperature at which all molecular motion stops? (What is the coldest temperature?)
Station 6 – Misc.
33) What is the term for when something sinks in water?
34) Does diffusion happen faster in hot or cold fluids?
35) How is diffusion evidence for molecular motion? (Hint: do you have to do anything to make diffusion happen?)
36) “Rail buckling” is when train tracks become bent due to heat. Describe why this happens.
37) Atom or Molecule?
a. H2
b. Ni
c. NI
