Question

Which are aspects covered by Bohr’s atomic model?

Electrons can have a measured radius.

Higher orbits have lower energies.

Electrons exist between orbits.

Electrons do not have energy, the energy is determined by the orbit.

Answer 1

Short answers with brief justifications:

1) "Electrons can have a measured radius." — No.
Bohr’s model does not assign a physical radius to the electron itself; it gives radii for the allowed electron orbits (e.g. the Bohr radius) but treats the electron as a point particle on those orbits.

2) "Higher orbits have lower energies." — No.
In Bohr’s model the energy levels are En = −13.6 eV / n^2 (for hydrogen). As n increases the energy becomes less negative (closer to zero), so higher orbits have higher energy (less tightly bound), not lower.

3) "Electrons exist between orbits." — No.
Bohr postulates that electrons occupy only the allowed stationary orbits; they do not have intermediate energies or continuous orbits between those levels. Transitions between levels occur by instantaneous quantum jumps with photon emission/absorption.

4) "Electrons do not have energy, the energy is determined by the orbit." — Effectively yes.
Bohr’s model assigns a definite, quantized energy to each allowed orbit; the electron in a stationary orbit has that orbit’s energy (so energy is determined by which orbit it occupies).

If you want, I can add the key Bohr postulates and the main formulae (r_n and E_n) for reference.
