How do you name the compound #LiCr_2O_7#?

1 Answer

It isn't a real compound the way it is written.


The lithium ion has a charge of +1.
The dichromate ion (all the other stuff) has a charge of -2.

Your positives and negatives don't balance each other out so the formula isn't a real compound.

However, if you meant #Li_"2"Cr_"2"O_"7"#, that name would be lithium dichromate.
