Get Bohr Model Practice Worksheet Answers

The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus (Figure 1). These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells.

This model was proposed by Niels Bohr in 1915; it is not completely correct, but it has many features that are approximately correct and it is sufficient for much of our discussion.

THE BOHR MODEL'S KEY POINTS It orbits around the core in a fixed size, fixed energy orbit. The energy of the orbit is proportional to its size. The lowest energy is in the smallest orbit. Whenever an electron transitions from one orbit to another, it absorbs or emits radiation.

Main Points of the Bohr Model The energy of the orbit is related to its size. The lowest energy is found in the smallest orbit. Radiation is absorbed or emitted when an electron moves from one orbit to another.

Summary The Bohr model postulates that electrons orbit the nucleus at fixed energy levels. Orbits further from the nucleus exist at higher energy levels. When electrons return to a lower energy level, they emit energy in the form of light.

Niels Bohr worked on the Manhattan Project during World War II, which eventually led to the development of the first atomic bomb. ... Soccer was important to Bohr, and he even played on a college team. ... Bohr had six sons with wife Margrethe, but two of them died during his lifetime.
