Question

Use Lewis electron dot diagrams to illustrate the chemical bond in the following items. Identify if its ionic or covalent

1. Magnesium Iodide (MgI)

Answer 1

Magnesium iodide (MgI2; not MgI) is an ionic compound. You should know this because it is made up of a metal (Mg) and a non metal (I). I can't easily draw on this platform, but it would be something like this....

I^- Mg²⁺ I^-

put 8 electrons around each I^- (4 electron pairs) and no electrons around the Mg²⁺
