A diverging mirror is a curved mirror that can be bulge outside towards the source of light called a convex mirror or inward away from the source of light called a concave mirror.
A convex mirror is a mirror that forms an image bigger and but right side up or exact as the object direction also called a virtual image. It appears to be bigger than the real object and not upside down as concave mirrors.

It will give it to an atom with more electrons. For example, Lithium (which has 1 valence electron) would give it to an atom that has more than 4 valence electrons
The oxygen wants to have a full valance shell and magnesium has just enough extra electrons to fill it.
