I need help with these questions
If ionic compunds are composed of charcg particles (ions) why isnt every ionic compund either positvely of negativaley charged
What is the net ionic charge of every ionic compund?
Write formulas for compunds composed of these pairs of ions
a.Na+, O^2
b. Sn^4+, S^2-
c. K+, Cl-
d. Mg2+, N^3
we never got books the teacher just wants us to do it in class but im not getting these questions so please help!

Part one: the charges cancel each other out
The net charge of every ionic compound therfore is 0
a. Na^+1 and O^-2 is simple take the exponents and place them as subscripts underneath the opposing element...so you come out with Na2O (that is Sodium with a subscript of 2 and Oxygen)
b. Try solving it first then look at the answer...Sn has a positive charge of 4 S has a negative charge of 2...SnS2 because 4/2 is 2
c.this one is easy...each has a single positive or negative charge, just write them together.
d. Magnesium with a positive 2 charge and Nitrogen with a negative 3 charge...take the exponent from one and put it as the subscript of the other...the answer is Mg3N2 I hope you learned something from this.

So cutting by way of all the bullshit, you prefer us that can assist you you pretend lesson plans which you have been in no way assigned and chemistry homework which you in no way did so your instructor delivers you a grade which you in no way earned? what's your backup plan whilst your chemistry instructor tries to make certain this with the instructor on the quite a few college? Or would desire to we watch for that question for next week? i don't think of i'd be doing you any favors if I "helped" you, yet i are conscious of it is going to take you a protracted time to realize that. Suck it up and play the enjoying cards you're dealt.

Get out your text book and study. If we give you the answers then we would be hurting you and not helping you. You need to study. Find a friend and study together if you cannot do it alone. Ask your teacher for extra help and guidance. Get a tutor etc. Help is fine when you need it, but asking for answers on the net is not helpful!
