Question

How do you draw the Lewis dot structure for `Cal_2`?

Answer 1

For calcium iodide, an ionic solid, we conceive of `Ca^(2+)`, and `2xxI^-` ions.

Explanation:

Calcium metal has been oxidized to give the `Ca^(2+)` ion, whose electronic structure is akin to that of closed shell `[Ar]`, and iodine has has been reduced to give closed shell `[Xe]`.
