Explanation: The valence of Mg is +2 which means it can give two electrons to any other element thereby forming chemical bond. As we can see, there are two Oxygen atoms on the left, so we must put 2 on the right side before Magnesium Oxide. How was Thomson's model of the atom valuable, even though Rutherford's experiment showed that the model was wrong? For this, there is requirement of an element which has valence of -2 or an element which has a deficiency of 2 electron to reach stable state.
