Bunny's Chemistry Questions

You guys usually don't know the answers either, but it's worth a shot.

how do I figure out how many electrons are in a positive ion?

:cheers2:

 

can't you ask a simple question, like 5+4=?

i can answer questions like that

 

I dropped math this year. Stats would have been the end of me, if chemistry doesn't take me first.

 

Anything you ever wanted to know, but were too ashamed to ask

i'm having trouble navigating it. But i posted my question there. Hopefully someone responds.

 

Whats the question 10% chance I know

 

how do I figure out how many electrons are in a positive ion?

 

*sigh*


...and to think, I used to know things like this....

 

Hmmm I do know but I can't explain

 

Question #712 was mine

 

I dont know, all I know is that they have more electrons than protons and that's what makes them positive.

I dont think there's a specific amount.

 

oh thank you so much! I had no idea how that worked. Gah! Thank you!

 

Everything is relative.

Write that on your homework in big letters...

And impress your teacher with your lack of wit.

 

An atom can gain or lose electrons, becoming what is known as an ion. An ion is nothing more than an electrically charged atom. Adding or removing electrons from an atom does not change which element it is, just its net charge.

For example, removing an electron from an atom of krypton forms a krypton ion, which is usually written as Kr+. The plus sign means that this is a positively charged ion. It is positively charged because a negatively charged electron was removed from the atom. The 35 remaining electrons were outnumbered by the 36 positively charged protons, resulting in a charge of +1.

You welcome, but Im not chemistry saavy at all, so you might want to double check that.

I actually checked for you, because I had my doubts.

And it's the opposite. A positive charged ion has FEWER electrons than protons and the negatelive charged one has more electrons than protons.

 

An ion is an atom or molecule which has lost or gained one or more electrons, giving it a positive or negative electrical charge.
A negatively charged ion, which has more electrons than it has protons, is known as an anion (ἀνά ana: Greek 'up') (pronounced /ˈænaɪən/; an-eye-on). Conversely, a positively-charged ion, which has fewer electrons than protons, is known as a cation (κατά kata: Greek 'down') (pronounced /ˈkætaɪən/; cat-eye-on).


Wikipedia.



I remembered something along these lines from my Chemistry class back in high school, but my memory is fuzzy.

 

I love wikipedia. I have it on my phone

 

just remember PROtons are positive
electrons are negative, neutrons are neutral, and ions have gained or lost one electron, depending on the element.
the atomic number, or the number above the column in the periodic table, is the number of protons/electrons in a nucleus of the (neutral) atom. if it is ionized, or non-neutral, the number of protons remains the same and the number of electrons is either +/- one.
