Elementary
What are the three elementary (basic) subatomic particles, and which one is not found in the nucleus?
Proton, Neutron, Electron
The electron orbits around the nucleus
Water is cohesive. This means it bonds with what?
Itself!
Adhesion is when it bonds with other things
What is the name of the branch of chemistry that deals with the exchange of heat?
THERMOchemistry
I have 2 moles of oxygen. How many oxygen atoms do I have?
2 * (6.02 * 1023)
What does the atomic number of an element tell us?
The number of protons
What is the group on the far right side of the periodic table that doesn't bond with any other atoms?
For an extra 100 points, why is this?
The noble gases
Because they have a full set of valence electrons!
Wow, it's taking a while for my water to boil! What property of water causes this?
It has a high specific heat capacity
I like the number .000010357, but it's not very scientific. Can you rewrite this number in scientific notation?
1.0357 x 10-5
According to practices in folklore knowledge of a true name allows one to affect another person or being magically. It is stated that knowing someone's, or something's, true name therefore gives the person (who knows the true name) power over them. What is Mr. Garfield's first name?
Clay!
Usually an atom has the same number of protons and electrons. What do we call an atom when this number is not balanced?
An Ion. Example O2-
a) How many valence electrons does an element want around it?
b) Why are they called valence electrons?
8, the octet rule
They are called valence because they are the outermost layer of electrons
I place a marshmallow over a fire. Does the marshmallow undergo an exothermic, endothermic, or heat neutral reaction?
Endothermic, it absorbs heat.
I have a balloon! It is .082 Liters large, the gas exerts 20 atms, and there is 1 mole of helium in it. How hot will the helium be?
20 degrees KELVIN
Although Mr. Garfield can only speak one language because he isn't very smart, his grandparents spoke many more. His grandfather could speak 7 languages fluently! Name one of the two places Mr. Garfield's family comes from
Egypt and Eastern Europe
What type of decay changes an atom from one element to another element?
Nuclear (alpha) decay)
This is because protons define an element, and they are in the nucleus
When atoms bond with other atoms, what value determines what sort of bond they will form? What is an example of one type of these bonds?
Electronegativity
Pure Covalent
Polar Covalent
Ionic
Kelvin is a peculiar system of measurement, but it makes a lot of sense for chemistry. What is important about 0 degrees kelvin?
It's absolute 0, the coldest it can get
My hot dog has a half life of 30 seconds. How long will it be before I eat 7/8 of my hot dog?
90 seconds
Mr. Garfield is very insecure and vain, and does not want people to know his age. How old is Mr. Garfield? +/- 2 years
24 years old
