I don't understand Chemistry

An am extremely jealous of those that do.

Moles and Avocados are best left to the Mexicans

If you can cook you can understand chemistry.

Food is edible chemistry.

If you want to start easy go with yeast: learn to home brew beer and make you own bread.

Chemistry is the Science of Things That Go Bang.

Finding out how to make things go bang is what defines us as males. Thus, SFTS can no longer be counted as a male. A metro at best.

Pretty simple no, neutrons are mass, and protons and and electrons bind together

Well, that is clearly wrong. Protons and electrons hate each other. The nucleus is the culmination of neutrons and protons, the main source of mass. Electrons just like to fly around the nucleus.

Neither of these are really enlightening towards understanding the fundamental beauty of chemistry that is essential to properly understanding what it is about. Another "enlightening" definition I have come across is that chemistry is really the study of the electron.

Chemistry is the study of matter but bounded to only the dimensional scales that us humans can actually manipulate, which at this point is down to the individual atom (to go any further down is probing the nucleus which begins to enter the realm of particle physics). Everything that constitutes Chemistry is essentially the numerous relations and principles repeatedly observed through empirical experimentation over the last 400 years.

Just for anybody curious visiting this thread, there are really good starter Chemistry videos at both Khanacademy.org as well as the CrashCourse Chemistry series which is currently ongoing.

Bee vomit and yeast poop makes booze; all ye need to know :laugh4:

Protons have no mass

Protons have a mass very similar to Neutrons.

Photons are mass less (that is why they travel at light speed).

nope.

Neutrons are slightly heavier then protons. But not hugely so, together they are classed as nucleons.

If neutrons are free ie they are not bound to a proton they will decay. The neutron will split into a proton, an electon an an antineutrino.

Now to really mess with your mind it is possible to use that information to figure out the ratio of neutrons to protons in the universe.

I tried but he doesn't pick up the phone for some reason. But protons have no mass. They sit in the core of an atom and keep electrons in check with magnitism, plus and minus, atoms can be stable or unstable depending on the amount and the number of spheres of electrons. That is basic chemistry, atoms can merge and form molecules

That is indeed both basic and correct, but protons still do have mass.

Protons have mass - electrons and photons have negligible mass.

Let me put it this way. If protons have no mass, the sun started out pretty much mass less and is slowly creating more mass. That would in turn make us slowly falling into the sun (not counting that a mass less sun wouldn't be able to keep any planets in the first place). I think Pape is correct and you mixed up photons and protons on the mass matter.

Photons has no mass, although they still do have momentum. With the Higgs particle confirmed, it means that photons doesn't interact with the Higgs particle, afaik.

Correct that the electron mass is negligable compared to a proton.

Photons are the protestants of the world of chemistry.

Protons were discovered by Ernest Rutherford - a home schooled New Zealander.

They have a mass of 1.6726 x 10^-27 kg each.

Neutrons 1.6749 x 10^-27 each.

So neutron is heavier but not by much.

Electrons are a mere 9.109 x 10^-31 kg

Electrons are to Protons what grams are to kg (~ three orders of magnitude)

Sure they but they need a negative

Oops, I'll leave this here so you can have a laugh at me and mock my very existance

Not laughing at you. Just sad that school missed teaching you science.

Chemistry is about how atoms and molecules interact; psychology for molecules. It is a crossroads between biology and geology and it uses physics to describe the models of the atom and molecules.

Chemistry defines elements by the number of protons they have:
1 proton = hydrogen
2 protons = helium
3 protons = lithium
4 protons = beryllium
5 protons = boron
6 protons = carbon
7 protons = nitrogen
8 protons = oxygen

That's the first eight and most important to us as a large chunk of biology uses carbon, oxygen, nitrogen and hydrogen.
Oil is essentially different combinations of Carbon and Hydrogen. Whilst alcohol is composed of carbon, hydrogen and oxygen.

My favorite thing to do every time I get lost in my head. Watch Khan Academy and go to Mass.

All you mention are molecules, atoms have only tree building stones.

Yes, but depending on how many of those they have you get different atoms.

IIRC their numbers are usually equal, so oxygen would have 8 protons, 8 neutrons and 8 electrons, though I'm not sure about the neutrons, IIRC sometimes they are not equal to the protons. If there are less electrons than neutrons you have an ion, it has an overall positive load. Ionisation is basically when an electron is kicked out of an atom by something from outside. I forgot what it's called when there are more electrons, could be isotope but IIRC isotope was some other deviation where it's the same element but has more neutrons or protons or something.

I know it's important and interesting but somehow I'm not that fond of chemistry... :sweatdrop:

The number of protons determine the element. Protons are electrically positive.

If there are more or less electrons then protons it is an ion. Typically it is less when the atom is heated and it 'sweats off' an electron. Electrons are electrically negative.

Neutrons are electricall neutral. An element can have multiple isotopes for instance Carbon 12 and Carbon 14.
The element Carbon has 6 protons. Carbon-12 is 6 protons and 6 neutrons. Carbon-14 is 6 protons and 8 neutrons.

I'll run the basics for you. You know some of it, but have other things mixed up.

That's 3 types of building stones for normal matter. Protons, neutrons and electrons.

Protons are positivly charged and determines the element, like Pape pointed out.

Neutrons are neutrally charged and keeps the protons together in the atom core. Their number also decides the isotope, which have slighty different properties. The biggest influence has to do with stability, which causes that some isotopes are radioactive. For example C14 (Carbon-14) is radioactive, while C12 and C13 are stable.

Electrons are negativly charged and are balancing protons, so they are the same number in atomic form. Electrons moves very easily though, creating ions, atoms and molecules that are having a charge.

Molecules are when 2 or more (up to many, many more) of atoms are bound together to make a specific unit. Those molecules does in turn interact with eachother, forming everything we see, since all molecules by themselves are very, very small.

Thanks, I knew about the electrical stuff but wasn't sure about the isotopes, makes sense though.
What I was thinking about regarding the ions were probably anions and cations. I just remembered there were different names depending on whether they're positive or negative.

Chemistry is that special magic that allows boys and girls to get together, and after they get along well enough, they can make more boys and girls. When that special magic fails, some people resort to

That much I know, i made a mistake when I said protons have no mass, a pretty stupid one as neutrons would have no other way to keep a hold of them. Cancelled out I guess

Not stupid at all. Most science is really poorly taught at school. Meaning most kids don't have a chance of understanding it.

Doesn't help that we pay science teachers so poorly that they have plenty of other higher paying options.

I was lucky and had some of the better ones as teachers. One of the next generation student teachers we had to teach the periodic table to them in chemistry class. The new set had plenty of biology science teachers but not enough chemistry teachers.

Can't expect students to learn what their teachers don't know.
