These aren't from any sort of schoolwork, I'm just a layman whom seeks academia, so if any of you who dabble in physics could answer some of my questions I would be appreciative.

1: What types of atoms are there, such as, are there only some, or are there infinite possibilities? I know of the carbon atom.

2: Is there any known basis for atoms? It seems as if the structure of a house needs a foundation that there would also need to be a foundation for the foundation, House - Foundation for the house - Planet (foundation for the foundation) - Universe (Foundation for the planet) So wouldn't it be appropriate that atoms would have a foundation?

3: What is the "Higgs Boson"? Is this something out of pseudo science? I've heard it barely ever and only as some sort of long awaited holy grail among physicists, I don't know the first thing about it if someone could clarify.

4: This is almost a retread of question two, but how are objects existent as physics sees it? Is there such thing as one singular atom, and if so, what would it be? Would it be a thing? Such as, from what I think I know, objects are made of components, such as trees are made of wood, and then wood is made of.....? I don't know the process by which it furthers in gradient. It would be:
 
tree - wood - Huh - atoms - Huh

from what I know of physics.



5: They say atoms are the basic unit of matter, so then what is energy made out of? Or is energy just a reflection of matter?

6: E = mc^2, from what I gather, energy = mass multiplied by the speed of light squared. So is the mass multiplied by the speed of light strictly mathematical? Or is mass that is moving at the speed of light^2 at that point energy? How does this equation work itself out basically?

7: What is the speed of light? Is it a static value or does it vary? I assume it wouldn't vary.

8: Are there different types of light? Not lightbulbs, like florescent and such, but are there different types of light itself? Or is it all the same? I know there are different types of rays, x-ray gamma-ray et cetera, but I don't know if rays are lights? The sun has rays, but are rays the same things as the light that it gives off?

9: Is it possible to change matter into energy or energy into matter? Does this have anything to do with the process of atom splitting?

10: How does atom splitting work? What exactly is undergone to split atoms and why is the result of splitting atoms (atleast the hydrogen atom) an explosion? E = mc^2 says that mass multiplied by the speed of light squared would be energy, so is this to say that every human being, having mass, has the potential to be hundreds of atomic bombs?

11: Are energy and mass two sides to the same coin or are they two separated things? I know that
the states of matter are liquid solid and gas, but then what would energy be? Wouldn't energy technically be a state of matter if E=mc^2?

12: What is fire comprised of? Is fire in any way related to plasma?

13: What is plasma? What is it made of?

Thank you very much if you took the time to answer any of my questions, there are more, but I'd rather not crowd up a single question with 50+ questions, especially as you see there are already multiple questions within each question, so I sort of cheated, but anyway, thank you very much for the time.

1. there are many different types of atoms. here is a handy list. http://www.webelements.com/atoms.html

2. i think what you are asking is what are atoms made of. if that's it, atoms are made up of protons, neutrons, and electrons

3. Higgs Boson is the theoretical particle that gives everything mass

4. i think i answered this in 2

5. atoms are not really the basic unit of matter. they are composed of smaller particles. which are also comprised of smaller particles.

as for what energy is made out of. that is a good question. no one really knows. no one even really knows if that is an appropriate question. some just consider energy a property of the system.

6. energy = mass times the speed of light squared. so, i think to answer your question energy is equal to the mass of whatever you are measuring multiplied by the squared speed of light.

7. most people consider c (speed of light) a constant. it is approximately 186,000 miles per second. there is a theory that the speed of light is variable. and has changed over time, but this is an unproven theory. for our purposes, the speed of light is a constant.

8. everything you listed is light, just in different wavelengths. light is light, and it is more varied that you can see with the naked eye.

9. yes and yes

10. the process by which atoms can be split is long and complicated. but you basically have to overcome the nuclear force that is holding the atom together. the result of splitting is not always an explosion. as for the potential to be atomic bombs, not really, but the energy is there.

11. no, energy is not really a state of matter. energy is a property of matter would be a better way of saying that imo.

12. fire is basically hot gases, it is kind of a precursor to plasma, but not a prerequisite

13. plasma is basically gas, ionized gas to be precise.
