Nuclear charge and electron energies

Question: The greater charge of a nucleus in a many-electron atom, the stronger it attracts the electrons and therefore lowers their energy. Why would an increase in nuclear charge result in lower energy?

Answer: If the electrons are strongly attracted, then the tendency for them to escape deceases. This means that the system becomes more stable and the more stable the system is the lower is its energy. Remember that nature favors stability and low energy.
