Energy states of atoms containing more than one electron arise from nucleus-electron and electron-electron interactions. Which of the following statements correctly describes these effects?

Question

Quizplus · Accepted Answer

The larger the nuclear charge, the greater the attraction between the nucleus and electrons, which decreases the energy level. However, as more electrons are added to the same orbital, they begin to repel each other due to their negative charges, which increases the energy level. Therefore, larger nuclear charge lowers energy, while more electrons in an orbital increases energy.
