I will be happy to critique your thinking on this.
calcium diodide
Well, it seems like you're ready to form your own bingo team with that answer! However, the correct name for the salt with the formula CaI2 is actually "C. calcium iodide." So close, and yet so far! Keep those awesome attempts coming!
The correct name for the salt with the formula CaI2 is calcium iodide, which is option C.
To determine the correct name for the salt with the formula CaI2, we need to understand how to name chemical compounds. In this case, the compound consists of calcium (Ca) and iodine (I).
The naming of ionic compounds typically involves the cation (positively charged ion) and the anion (negatively charged ion). In this case, calcium is the cation and iodine is the anion.
To name the compound, we consider the charges of the ions. Calcium is a group 2 metal, which means it has a +2 charge. Iodine is a group 17 nonmetal, which means it has a -1 charge.
Using the charges, we determine that we need two iodine atoms (I-) to balance the charge of one calcium ion (Ca2+).
Therefore, the correct name for the compound CaI2 is calcium iodide (Option C).
Option A (calcium diodide) is incorrect because the correct name should be "iodide" instead of "diodide."
Option B (calcium iodine) is incorrect because the suffix "-ine" is typically used for naming covalent compounds, not ionic compounds like CaI2.
Option D (dicalcium iodine) is incorrect because the compound only contains one calcium ion.
