The Electron Configuration
Back to all problems
ANSWERS OPTIONS
A
Yes; The orbital energies are defined by the atomic number and not by the number of electrons.
B
No; Orbital energies in multi-electron atoms are different for each orbital due to repulsions between electrons.
C
Yes; Atoms with up to 2 electrons can have degenerate orbitals within a single energy level.
D
No; 2s and 2p are two separate orbitals so their energies will be different in any condition.
