Question

Determine the best formula for reacting elements.

calcium and iodine

A. Cal
B. Cal2
C. Ca2l
D. Ca2l2

Answer 1

my freind the best anwer would probably be B

Answer 2

Answer: Option (B) is the correct answer.

Step-by-step explanation:

Calcium is a metal and iodine is a non-metal. So, when calcium and iodine combine with each other then calcium will donate its excess of electrons to the iodine atom. Thus, it will form an ionic bond.

When calcium reacts with iodine then it results in the formation of calcium iodide.

The reaction equation will be as follows.

`Ca^(2+) + I^(-) \rightarrow CaI_(2)`
