Answer:
The electronic configuration of the magnesium atom shows that it has two unpaired outermost shell electrons while that of oxygen shows that it has six outermost shell electrons with two of them unpaired.
By means of elecron transfer, magnesium atom donates its two electrons to the oxygen atom to now have a charge of +2 while the oxygen then has a charge of -2. This results in an ionic bonding between the two atoms.

Answer:
D: When the acidity of a solution increases, the pH increases.
Explanation:
It is totally wrong to assert that when the acidity of a solution increases, the pH of the solution will increase
The right answer is that when the acidity of a solution increases, the pH value decreases.
- The pH scale records the level of acidity and basicity of a substance.
- It runs from 1 to 14
- From 7 to 14 signifies increasing basicity
- As the acidity of a substance increases, the pH value reduces.
- For acids 1 is the highest acidity levels.
