Question

how did niels bohr describe electrons in his atomic model?
their energies can have any values.
their exact positions cannot be known.
they have high probability to be found in certain regions.
they orbit the central nucleus in discrete paths.

Explanation:

• In Niels Bohr's atomic model, electrons orbit the nucleus in specific, discrete (quantized) energy levels or paths (orbits).
• The first option is incorrect as Bohr proposed electrons have discrete energy values. The second and third options relate to the quantum mechanical model (like Heisenberg's uncertainty principle or electron cloud concept), not Bohr's model.

Answer:

D. They orbit the central nucleus in discrete paths.
