Chromium triiodide contain 12,005 09 % chromium.
a CrI3 is a chromium 3
Cr can be either 2+, 3+ or 6+. I is 1-. So a single [Cr]3+ and three [I]1- are needed to balance the formula. [[Cr]3+] + 3[I]1- ---> CrI_3
CrI3 contains the Cr3+ cation.
Chromium is very reactive and reacts with many elements; for some compounds of chromium see the list below.
Chromium has two electrons in the outer most shell.
