In Bohr's model, the radius of an electron orbit is proportional to n²/Z, where n is the principal quantum number and Z is the atomic number. For hydrogen (H), Z=1, so the radius increases with n. The n=3 state of H has a larger radius than the n=1 or n=2 states of H, and larger than the n=3 state of Li²⁺ or n=4 state of He⁺ due to their higher Z values.
