The Modern Atomic Theory

Question 3 • *26-27 CFISD TX-Chemistry A CR

Which are aspects covered by Bohr’s atomic model?

Answer
A
Electrons can have a measured radius.
B
Higher orbits have lower energies.
C
Electrons exist between orbits.
D
Electrons do not have energy, the energy is determined by the orbit.

Explanation

In Bohr’s model, electrons occupy specific allowed orbits, each with a definite radius, so the orbit’s radius can be calculated or measured. Higher orbits have higher energy, not lower energy, and electrons cannot exist between the allowed orbits. Electrons do have energy; its value depends on the orbit.
