the smaller the value of n the lower the energy and the closer to the orbital is to the nucleus true or flase

True

Explanation:

This is because when you move across the periodic table, the number of atoms increase and the number of energy decrease downward. N represent energy level . n1 is the closest in the nucleus and n7 is the farthest. The farther the n in the nucleus, the higher the energy in the orbital. The smaller the n, the lower the energy and closer to the orbital.
