Which statements are true for multi-electron atoms?  [Select all that apply.]多项选择题

The Bohr model describes the electron energies.

The energy levels for these systems depend on the shape and size of the orbitals.

The presence of multiple electrons increases the attraction of electron to the protons in the nucleus.

The orbital energies are a function n, ℓ, and the effective nuclear charge, Zeff.

When there is more than one electron in an atom, the orbital electrons repel each other.
