Aha...answer found here. This thread can be closed :)

Which elements "travel in pairs"? This isn't exactly "homework help", just something that's been on my mind for a while. I know that when writing chlorine, oxygen and hydrogen by itself, you need to add a two. Why is this so? And also, what other elements "travel in pairs"?

Oh well, thanks anyway. I didn't know it was a "higher level" question, seeing as my teacher gave it as homework (I'm in grade 9, by the way). Again, thanks anyway. I think this thread has served it's purpose since I got the answers.

*bump* Please, this is the only question I'll ever need to ask here and I need the answer ASAP - I've done all I can with them, please, someone show me the answers!

Damn, in my classes we've just been using valencies..=/ (P.S. thanks for the links) Edit: Uh, have I shown sufficient effort?

Formula for calcium hydroxide=CaOH; magnesium hydroxide=MgOH. Regarding the charges on the ions, I haven't learned that too well as of yet, however I have learned valencies. Calcium's valency is 2(+); magnesium's valency is 2(+). Furthermore, hydrochloric acid=HCl; nitric acid=HNO3.

(Oh, sorry about the misplacement of the thread =/) My book hardly tells me anything and I have an awful teacher; all I need are these three answers to work off; sorry if I sound kind of demanding, but I honestly don't want mean to sound like I am.

I'm assuming this is the correct forum, please tell me if it isn't so I'll know if future. I'm new to the whole formulae thing, and need some help with some (presumably) easy formulae. How would I write the following in both words and symbols? I've done as much work as I know how to do, so...
