Which way do periods run on the Periodic Table?
Left to Right or Side to Side

What determines the number of each element in a chemical formula?
Subscript
100
In order for something to undergo a chemical change, what has to be created?
Something new
100
What is the formula for speed?
Speed = Distance / Time
200
Which two subatomic particles make up the mass of an atom?
Protons and Neutrons
200
What determines the reactivity of an element?
The number of valence electrons
200
What does the coeffecient determine the number of in a chemical formula?
The number of molecules
200
Tearing paper, breaking glass, and cutting hair are NOT examples of chemical changes. Explain why.
Nothing new was created
200
What causes an object to move?
An unbalanced force
300
How is mass number different from atomic mass?
Mass number = rounded version of atomic mass, used for APEMAN. Atomic mass = the actual mass of the atom, found on the Periodic Table.
300
Elements that are most similar to one another, or have the same reactivity, will be located where on the Periodic Table?
In the same group
300
CHC3O4OH2 How many total atoms are there in this chemical equation?
12

A piece of bread is placed in a toaster. After 4 mintues, the bread pops up and is now toast. Did a chemical change occur? Why or why not?
YES Something new was created. Can not be changed back. Color change, temperature change.

If I am pushing 4 stacks of books (each with different masses) with the same amount of force, which stack of books will accelerate the most?
The stack with the LEAST mass
400
Write out what APE MAN stands for and include math signs.
A(atomic #) = P (protons) = E (electrons) M(mass#) - A (atomic #) = N (neutrons)

Explain where the nonmetals, metals, and metalloids are on the Periodic Table.
Metalloids - on the stairsteps (except aluminum) Non-metals - to the right (dont forget hyrdrogen) Metals - everything else (including aluminum)

The atom of a certain element has 11 protons and 1 valence electron. Is this element highly reactive or not highly reactive and why?
NOT reactive. Only 1 valence electron.
500
What group and period would an element with 7 valence electrons be located and would this be a metal, nonmetal, or metalloid?
Group - 17 Period - 3 Non-Metal

What are the 5 pieces of evidence of a chemical change?
1) unexpected color change 2) unexpected temperature change 3) bubbling or fizzing 4) formation of light 5) formation of a solid
500
How is acceleration calculated?
Final velocity - Initial velocity / Time
