Electrons and Protons; 2 questions?

The questions are not as dumb as they sound, so please do answer, as they sometime makes me think.

  1. Why electrons and protons have opposite but exact charge? These exact charges keep atoms stable and have atoms with exact number of protons and electrons - which leads me to my next question …

  2. Why do we have exact number of electrons and protons in the universe?

Re: Electrons and Protons; 2 questions?

idk.

let me add 2 questions too.

  1. what the hell is charge.

  2. why are there two kinds.

  3. why do like charges repel, and unlike charges attract.

i cant really count.

Re: Electrons and Protons; 2 questions?

Like charges are like Queer and PCG.

Hope that answers your curiosity.

Re: Electrons and Protons; 2 questions?

I'm just thinking out loud here but I assume the reason protons and electors have opposite charges is because it leads to negatively or positively charged atoms. If there wasn't this charge atoms would not be able to form bonds and complex molecules etc. If there was only neutrons the loss or gain of neutrons wouldn't make any difference but when an electron is lost or gained a charged atom is formed (ion). I know there are other types of bonds too but again I think it's the opposite charge of protons and electrons and their placement that allows bonds to take place.

hmm not sure about the second question but I guess so at the end all atoms are chemically stable.

Re: Electrons and Protons; 2 questions?

stability of atom is the effect, not cause of the same magnitude of charge

Re: Electrons and Protons; 2 questions?

hmm I'm not quiet sure if I understand your post lol. But what I was saying is yes an atom is electrically stable at equal number of protons and electrons but not chemically stable so electrons are gained lost or shared to form bonds to achieve chemical stability right?

Re: Electrons and Protons; 2 questions?

Yes that is true.

Re: Electrons and Protons; 2 questions?

Therefore, if there weren't protons or electrons and only neutrons chemically stability wouldn't be possible and more over if atoms didn't bond there wouldn't be any molecules or tissues etc formed.

Re: Electrons and Protons; 2 questions?

I think net charge of the earth is 0? So # of protons = # of electrons in the earth?

By extension same applies for the universe?

Re: Electrons and Protons; 2 questions?

  • That's asking why the laws of physics are what they are. Some theoretical physicists might know. I wonder if there are any on GS.

  • Is this true? I never thought of the universe being "in balance" in terms of charge. Interesting.

  • Re: Electrons and Protons; 2 questions?

    Oh yes, that is true. Also if there were no electrons and protons, stuff would not have the solid feel and things would easily pass through each other. DO you know that the reason you stand on earth and dont fall through it is not because your body is solid (each atom and its nucleus is like a ping pong ball sitting in the middle of a football field, so each atom has that much empty space and two atoms can pass through each other), but because your electrons repel the electrons of earth so you cant pass through.

    net charge is definitely zero

    I read that somewhere, and I know that it sounds interesting but at least visible universe is. Now I know that molecules dont have equal number of elctrons and protons and most of the universe is in form of melecules and not free atoms, so although most of the universe might be nuteral in terms of charge, that does not mean that it has equal numbers of electron and proton.

    Re: Electrons and Protons; 2 questions?

    My opinion:
    1. They just do. Everything discussed so far seems like a consequence of the fact and not the reason behind it.

    Re: Electrons and Protons; 2 questions?

    i want to know the reason behind it. DO you have an pinon on that?

    Re: Electrons and Protons; 2 questions?

    i think string theory walay ullus have a few reasons for this. but me no undastand.

    Re: Electrons and Protons; 2 questions?

    My opinion is if its wasn't so then nothing would exist. :p

    Re: Electrons and Protons; 2 questions?

    At this point the only reasonable answer - because I said so!

    Re: Electrons and Protons; 2 questions?

    String theory walay ullus seem to have answer to everything. But its still an untested theory unfortunately.

    That is called Anthropic principle, which pretty much goes like

    Q. why the universe is like that?
    A. Because if it was not like that then we would not be here to ask that question

    Re: Electrons and Protons; 2 questions?

    Well thanks for naming it I didn't know it was an actual principle.
