What are the charges of the 3 subatomic particles that make up an atom?
Protons = positive
Electrons = negative
Neutrons = neutral
What is a compound and give an example?
Two of more elements chemically combined.
water, salt, etc...
What are the 6 signs of a chemical reaction?

What is the name of the richest man in the world?
Elon Musk
Which groups are the most reactive and least reactive?
Group 1 is Most reactive and Group 18 is least reactive.
What two parts make up an atom and which subatomic particles are located in that part?
Nucleus includes protons and neutrons.
Electron cloud includes electrons.
What is a subscript?
The small number that tells you how many atoms.
What is the formula for Density?
Mass divided by volume.
Who has the most number 1 hits of all time?
The Beatles
Describe where metals, non-metals, and metalloids are on the PTOE?
Metals are on the left and center.
Non-Metals are on the right.
Metalloids are in the middle right side touching the staircase.
How do you use an element box from the PTOE to find the amount of the protons, neutrons, and electrons?
The atomic number tells you how many protons and electrons.
To find neutrons, round mass and subtract the Atomic number.
APE MAN
How is a compound different from a molecule?
A compound has to have more than 1 element.
A molecule has to have more than 1 atom.
What units are used for mass and for volume?
Mass uses grams (g)
Volume uses (ml) when using water displacement and (cm3) when using l x w x h.
How long is a light year?
1 year
Explain what it means if elements are in the same period as opposed to being in the same family?
If elements are in the same period, they will have the same number of rings/shells/energy levels.
If elements are in the same family or group, that means they will have the same number of valence electrons and therefore share similar reactivity.
Describe what that Bohr atom model for Argon looks like...
P = 18
E = 18
N = 22
3 energy levels- 1st ring has 2 electrons, 2nd ring has 8 electrons, and 3rd ring has 8 electrons.
How many atoms are in Glucose?
24
A student wanted to calculate the density of an unknown object that has a mass of 13 g. They used a graduated cylinder with an initial volume of 5 mL, dropped in the object and read a final volume of 19 ml. What is the density of the object?
and Will the object float or sink?
.93 g/ml
It will float because it's density is less than 1.
Which President is featured on the $1,000 bill?
Grover Cleveland
