Is the Bohr model valid?

Answer 1

Naomi Aronson

It works well for modeling smaller elements, but as atom sizes grow, it becomes unworkable.

This model of electrons is frequently applicable in high school chemistry classes.

The Bohr model was an early attempt to describe the structure of atoms, proposed by Niels Bohr in 1913. Although revolutionary at the time and offering valuable insights into atomic structure, it has limitations and is not regarded as fully valid according to modern quantum mechanics. Nevertheless, it remains in use as a simplified model to teach fundamental concepts about atoms.
