It will be a metal, as gases have negative charges. Na has 1+ Cu has 2+/1+ K has 1+ Fe how ever has 3+/2+ Mg has 2+ So your answer is?
Astrophysics

You can also look at your compound and tell right away which one it is, as Cl has a charge of 1-, and you have to balance compounds as well.

so it would be Cucl?

Read what I've said and look at what your question is asking.

i am so confused. i suck at this

|dw:1435957321256:dw| the writing in pink represents the charge
Astrophysics

Fe has a 3+ ion and a 2+ ion
anonymous
  • anonymous
so this may be a stupid question but what Cl3 stand for?
Astrophysics
  • Astrophysics
Mhm ok, so it seems you've not learned how to "balance" the compounds, notice how in the periodic table I've put a 1- charge on the right side, and Cl falls into it right?
anonymous
  • anonymous
yes i see that
Astrophysics
  • Astrophysics
|dw:1435957604642:dw| you want to balance it out when you make a compound so they both have equal charged
Astrophysics

charges*
Astrophysics

so you have iron(iii)chloride now
anonymous
  • anonymous
but would it that mean that it would be 2+ because the 3+ and the -1? maybe i am over thinking it
Astrophysics

|dw:1435957694954:dw| if that helps
Astrophysics
  • Astrophysics
You are, you don't subtract/ add
anonymous
  • anonymous
okay i get it. thank you so much for your help ;0 )
Astrophysics
  • Astrophysics
You want to have a neutral charge, or let me simplify it more, you want the "elements" to have equal charges in the compound
Astrophysics
  • Astrophysics
Np, all makes sense right?
anonymous
  • anonymous
yes thank you
Astrophysics

So let me ask you one question, how would you make a compound of lets say magnesium nitride
Astrophysics
  • Astrophysics
Look at the periodic table for charges
anonymous
  • anonymous
it would be 2+ right
Astrophysics
  • Astrophysics
Well, you have |dw:1435957943479:dw| you can ignore that 2 for now it just means it's a diatomic element, but balance this compound
Astrophysics
  • Astrophysics
(ignore 2 for nitrogen)
anonymous
  • anonymous
so like MG,N-3?i know that its like if you have two that are the same its just the letters
Astrophysics
  • Astrophysics
No, notice how magnesium has a 2+ charge, and nitrogen has a 3- charge, we are looking for magnesium nitride, which would then be \[\huge Mg_3N_2\] easy as that

  • anonymous
ooo right you just flip the numbers i forgot about that. i am doing a speed class in collage and its going a little to fast lol
Astrophysics
  • Astrophysics
Well, it's not exactly flipping the numbers, if I gave you tin oxide, you would have |dw:1435958432367:dw|
Astrophysics
  • Astrophysics
Notice you have to simplify this one
Astrophysics
  • Astrophysics
|dw:1435958482990:dw|

oooo god this is getting crazy lmao
Astrophysics

Well this is all high school chem

You need to learn this before you can balance a chemical equation
