WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative. Even for an H atom in an excited state, the energy is negative, but it is less negative than for an atom in the ground state.
