I've asked my freinds and teachers many times, but they din't quite answer me. I know ions are electromagnetically charged (i think) and can be positive or negative.

I THINK that an Ion is an element with/without an extra electron.

Yeah. I read somewhere that an Ion... lets say of an hydrogen atom is an hydrogen atom with 1 more or 1 less electron, but the same number of neutrons and protons... i really aint sure about this.

Almost everything we do in my Chemistry class is realted to ions. The sorry thing being that I don't know what they really are. Here's a definition strait from my book:

Oh. But it has something to do with cathodes and anodes.. even if i don't know what theyt exactly are.

Cathodes and annodes are the two parts of a vacuum tube. That would be in ancient history class
. When the cathode is heated the extra energy causes the electrons to jump the vaccum to the annode. Pretty simple.Ions are atoms that either have more electrons or fewer electrons than they normally have. Ions have different reactions with other materials and are related to most of Chemistry. |

Ok...it's simple. Protons have posative charge. Electrons have a negative charge. Neutrons are...well, neutral. When an atom has an equal amount of electron and protons, the charges cancel each other. If an atom loses or gains an electron, the charge of the atom rises or lowers. If the atom loses an electron, the charge is posative. If it gains one, the charge is negative. Get it?

I know that. I'm not totally ignorant in physics.

If you take chemistry, before you start making reactions happen you need to know this to understand when certain chemichals will react with others. But then there's the little matter about atoms who normally will have multiple possible charges. For instance, iron has two possible forms of +2 and +4 charges so if you wanted FeO(iron oxide) you'd use iron atoms with +2 charge so that they'd cancel out oxygen's -2 charge. Or you could make FeO2 with the +4 charged iron. If you ever get a chance to take chemistry, go for it, it's fun if you get a good teacher.

Also, my chemistry class is not fun. The teacher makes us take notes, and then expects us to have mastered how to do something brand new with no real experience. So, I recommend that you not take a chemistry class.

Augh, chemistry rules so much...
Well, y'all got the ion question right. Ion = atom or molecule plus or minus an electron or electrons. But as for the cathode/anode thing, though, they aren't limited just to vacuum tubes. They're any two points over which there is a potential difference. Battery terminals are cathodes and anodes (cathode is black, anode red), as are two metals with different electronegativities next to each other. Just wanted to say that, and post in a thread about chemistry since I love it so much. --Guido http://andy.mikee385.com |
