Transcript of Chemistry
This is a positively charged particle. Electrons are drawn to it and vice versa. It is kept in the nucleus by the neutrons.
This particle has no charge, but it keeps the electrons away from the protons in the nuclei and vice versa.
When you rub against anything, you rub off some electrons. And I mean ANYTHING. Just some things more than others. If something rubbed off a lot of electrons, then it has more protons than electrons. The other thing would have a lot of extra electrons.
How it works
An atom almost always has the same amount of protons and electrons. That makes it neutral. However, that's boring. Fortunately, our atom isn't. It has more protons than electrons, so it's positively charged. The electrons in two atoms normally ignore each other, because their protons are closer than that other weird atom's protons. But they are usually attracted to just a few positive particles, when ours is a whole ATOM that was positive! So the electrons run over to our positive atom (attraction) with the protons in hot pursuit (attraction) and the neutrons scrambling after them to regain control (just what it sounds like). So it takes the whole atom, and starts a chain reaction. That's what makes the water bend.
The electron is negatively charged, and because of the attraction to protons and the repulsion of neutrons, it balances out and orbits the nucleus.
The Magic of Chemistry
Liquids are cool. Magnets are cool. But, liquid magnets!? Super cool! The iron attracts the liquid, causing it to form around it. It is called ferrofluid.
Here, I will show you what defines weight and density by stacking liquids in a bottle.
How it works
Simple answer: The other liquids are heavier so that they sink down to the bottom without mixing. But 'round here, we don't do "simple". So, a item's density is determined by how many particles there are per volume (amount). Let's say you have a kilogram of nitrogen-7 protons & 7 electrons-and also a kilogram of helium-2 protons & 2 electrons. Which is denser? The nitrogen. Since it is heavier, it sinks to the bottom if you put the two together, like in our experiment.
How it works
So, each electron has one magnetic field, and it is pointing in one direction. For something to be magnetic, all of the electrons' fields must all be pointed in the same directions, or it cancels out and is not magnetic. If it does have them all in the same direction, it is a magnet. Some materials are not magnetic, but can be magnetized while in a magnetic field. These are
. Some metals like this are called
