Properties of Matter
100
This is required to change something from one state of matter to another
What is energy
100
Only has one proton in the nucleus.
What is hydrogen?
100
Protons & Neutrons
What is in the middle of an atom?
100
2 Hydrogens combined with 1 Oxygen
What is a water molecule?
100
Liquid, solid, and gas
What are the three states of matter we discussed in class?
200
It emitted CO2 when you mixed the baking soda and vinegar.
How do you know there was a chemical reaction?
200
Because they have all of their outer shells filled.
Why are the elements in the row on the far right column more happy or stable?
200
Electrons
What orbits around the nucleus in shells?
200
Chloride and Sodium
What is table salt?
200
It turned green when Ms. Howell poured in the solution.
How do you know ammonia was a base?
300
Mixed salt in the water, and had an anode and cathode sitting down in the water, attached to wires that ran electricity through the solution.
How did Ms. Howell split off a Hydrogen molecule from water?
300
Because the rows have common characteristics, and the columns also have common characteristics.
Why did Mendeleev group elements together on the periodic table in the way they did?
300
Positive Charge, Neutral Charge, and Negative Charge
What is the charge of a proton, neutron, and electron?
300
Atoms are a part of everything on earth!
What is funny about the joke: You can't believe anything an atom says, because they make up everything?
300
Is locked in a lattice structure, molecules vibrate unless it is 0 degrees Kelvin, holds its shape without a container.
What is a solid?
400
what you get when you split or join the nuclei of atoms.
What is nuclear energy
400
The elements have more and more shells.
What happens to the elements as you go down the rows?
400
they keep the protons from repelling each other and tearing apart the atom.
What is one theory about why there need to be neutrons in the nucleus of an atom?
400
92
How many elements occur naturally?
400
Oxygen, nitrogen, some water molecules, some CO2
What is in the air we breathe?
500
That is what happened when Ms. Howell combined calcium carbonate with milk.
What chemical reaction heated up?
500
2 in the inner shell, 8 in the second shell, and 7 in the last shell
What is the electron configuration of Chloride?
500
because there is only one proton, so there isn't the need for a buffer.
What is the reason hydrogen has no neutrons in the nucleus?
500
barium, copper, aluminum, and strontium
What are some of the elements found in fireworks?
500
the property that allows oil to float on top of vinegar.
What is density?
