Question

Can you explain the Mg examples below on the slide? It is NOT an assignment; this is a slide from a professor lecture.

Periodic Trends and Chemical Properties. Main group elements to the left of a period tend to lose electrons to form cations with the same configuration as the previous noble gas. Mg Mg It is relatively easy to remove electrons until the next one removed would have to come from the core, at which point it becomes much more difficult. Energetically, the "pay-off" comes in forming an ionic solid, but it is insufficient to justify removing core electrons. Mg unfavorable Mg+ Mg²+ more unfavorable very unfavorable favorable Mg+X-(s) Mg²+X-₂(s) very favorable Mg³+ very favorable, but not enough Mg³+X-3(s)
