there is no such compound as CaI. Ca ion has a +2 charge and a I ion has a -1 charge. so, it takes two I ions to form a compound with one Ca ion.
so, it should be CaI2 and yes it is called calcium iodide.

CaI2 is calcium iodide, not CaI
however, Cal cannot be calcium because there is already a symbol for calcium
its Ca, like the abbreviation of california, except the 'a' isn't capitolized

Firstly, this question has been investigated by me long time able. I found out that it is quite confusing till I found out more about valencies and formulae writing in chemistry. Cal is calcium. It is impossible to be calcium iodide and the formulae for calcium iodide is CaI2.

i dunt think there is such a CaI compound. Ca is 2+ and I is - so it should be CaI2 and it is read: Calcium iodide.
