Answer:
False
Explanation:
The answer is false because unlike the main group elements, the transition metals have different valency. They exhibit variable valency and this is because of the presence of the d orbitals.
For question two, you figure out the amount of sodium atoms on the left and right side and the amount of oxygen atoms on the left and right side
So for two it would be 4, 1, 2
For question four, you figure out the amount of atoms on each side
So for four it would be 1, 2, 1, 2
