These are the questions I need help on.
Lydia
i know these elements but I can’t help you
Ok, thanks anyway.
Lydia
I know the elements but not a pro at them and I don’t know how to make a scientific formula
Um, gosh. Not sure this is completely the place to ask for chemistry help. But it’s an interesting question .
You need to think about the cation/anion that each component will form, and then how many of each ion will be needed to neutralise the other. For example, with calcium chloride, calcium forms Ca2+ ions, and chlorine forms Cl- ions. So you’ll need 2 chlorines to balance out the +2 charge on the calcium, so the formula will be CaCl2. Some elements can form compounds in 2 different states, so the name tells you what charge it has. So the Copper (II) bromide will have a Cu2+, and will need 2 bromines to balance it (copper can also come as a Cu4+).
Try to work out what you think it should be, and then use Google to check that it’s right (you could just Google all of them, but you probably won’t learn anything from doing that).
For the bottom section, you always put the cation first, and then the anion, usually with -ide at the end (but sometimes not). So the top one will be Mercury Fluoride. Again Google will help you check, but try to work it out first!
Hope that helps.

Wow! Thanks! I had to read it through several times (not the best at reading)
So for Indium hydroxide, it would be In(OH-)5 ??
Lydia
P.S. I know this is not the best place to ask (I’m sorry), but I didn’t really pay attention to naming Binary compounds. So here I am!
I had to Google indium, as I don’t think I’ve ever had a question on it before!
https://en.wikipedia.org/wiki/Indium says it can form either a +1 or a +3 ion. How many OH- does it need to balance each of those out? (I think the +3 ion is more likely, but technically either answer is correct).
Ok, thank you! Your explanation helped me out a lot!
Lydia
I genuinly wish that this is what I was learning, but all I get is fungi, fungi, fungi.
@jka2706 you lost me here.
@Lydia_Song if you dont mind telling me are you in highschool???
I’m in 7th grade but in a charter school, so we learn things way ahead of our grade.
Lydia
that explains why I am failing to understand
yep.
I know right. I have no clue what @jka2706 was even talking about
and I am in highschool too (freshman)
What’s a charter school
Like a private and public school combined
Lydia
Okay thank you 20 chara
