Test 1 Objective 5
I think that the atomic model in 2050 will look like it does now, with the current electron cloud, but the electrons will have a more advanced orbital. We will be able to measure the speeds of how fast they go, and we will be able to see how the atoms moves, as if in a circle or rapidly in random directions.
In 2100, I believe that we will see how atoms react with other atoms around them. So we will see how they bond, act, and react with the atoms around them. So there will be energy levels and charges around them.
In the year 2500, i believe that all atomic models will be 3D and holographic. You will be able to zoom, scroll, and learn facts about the elements all with the touch of a finger. We will have discovered many more elements, and there facts will tell us more on the building of the future atomic model.

Test 1 Objective 1 Answers
1. Electrons, Protons, and Neutrons.
2. Lavoisier believed and stated that the matter could not be created or destroyed, only change form.
3.J.J. Thomson.
4.Protons and Neutrons
5. Electrons
6. He thought that everything was composed of atoms, and atoms could not be divided. He also thought that everything had its own atoms (wood had wood atoms, air had air atoms, etc.)
7. Stated that there were electrons with a negative charge surrounded by a sea of positive charge. Created by J. J. Thomson.
8.The Bohr model consists of a nucleus that has protons and neutrons, and around it electrons that orbit in a circular pattern around the nucleus.
9. John Dalton's atomic model was just a block mass that couldn't be divided.
10. Schrödinger's Cat is a thought experiment that says if a cat was in a box with a flask of poison, a hammer that would break the flask, but only if a radioactive substance decided to release a particle. Since we don't know when or if the particle is released, we must assume the cat as dead and alive at the same time. The only way we know is if we open the box and look.
11. This experiment says since we don't know where electrons are exactly, we must assume them as in every possible spot at the same time.

Test 1: Objective 2
An electron is a particle within an atom creating a negative charge. They were officially discovered by Johann Wilhelm Hittorf, who was a German physicist. No one has ever actually seen an atom, much less an electron, since electrons are hundreds or thousands the size of atoms. But we almost never come across a discovery like this by accident. It is human nature to come up with an idea, and then try to support that idea with evidence. With the right equipment, it is very easy to see an electron. We can bounce things, such as neutrons or ELECTRONS!!! off of atoms. We can also track the movement of electrons by studying electricity.

Test 8
1. V=2,000cm cubed.
2.10gms per cm cubed.
3. As we know when a candle burns, it takes the wick and candle just sitting with potential energy, and causes it to catch on fire. Fire is a chemical reaction that releases chemical energy. It also releases light and thermal energy to keep us warm and bright. The flame moves, releasing kinectic energy. Since the electrons do not flow, there is no electrical energy involved when a candle burns. There would be electromagnetic energy released in light rays.
4.Boyles law is simple: if the pressure of a certain mass is increased, the volume will decrease.
Charles law states that if the temperature increases, than the volume will increase as well. If I had to tell my pet, I would give it a treat after every statement. If I had to tell my nephew, I would speak in Klingon.
5.V(arrow up) T (arrow up) P (arrow down)
V (arrow down) T(arrow down) P (arrow up)

Homework 10 Part 6
1. An acid is a substance with a pH of less than 7, and reacts with bases and metals. They usually turn litmus paper blue. The lower the pH, the greater acid there is.
2. Neutralization is when you balance out how acidic or basic something is through a chemical reaction... or making the pH 7. An example would be making salt.
3. An indicator is something that shows how acidic or basic something.
4.Corrosive is a substance that dissolves or disintegrates with its surroundings, such as a strong acid or base.
5. Hydroxide ion aka OH- is the ion created by a base with water.

Homework 10 Part 5
1. Mechanical and CHemical
2.Mechanical Digestion breaks down the food physically. Chemical Digestion breaks down the food into molecules chemically.
3.They lose a large part of the physical digestion and are not able to break down the food.
4. Mouth= 5,6, or 7
Stomach= About 2
Small Intestine= about 7
5. The mouth doesn't need much acid because it breaks down the food mechanically. The stomach however, relies on the acid to break down the food, thus needing a lower pH.
