Question

All of the following are true statements about the Bohr model of the atom except Question 9 options: To move from one orbit to another either up or down requires a change in the electron's energy—a change determined by the difference between the two energy values. Bohr proposed that electrons are distributed around the nucleus in a probability distribution fashion Bohr model proposed that the atom contains orbits of only certain sizes and specific distances from the atom's nucleus; electrons exist in these quantized energy levels. Lower energy levels are closer to the nucleus and higher energy levels are farther from the nucleus of an atom.

Answer 1

The incorrect statement about the Bohr model of the atom is that it proposed electrons are distributed in a probability distribution fashion. Rather, the Bohr model specifies electrons in fixed energy levels, and transitions between these levels involve precise energy changes.

Step-by-step explanation:

Among the statements about the Bohr model of the atom, the one that is not true is: Bohr proposed that electrons are distributed around the nucleus in a probability distribution fashion. Instead, the Bohr model posits that electrons orbit the nucleus at fixed energy levels. These orbits or energy levels are distinct; that is, the electron's orbit is quantized and can have only certain allowed radii.

In the Bohr model, to move an electron from one orbit to another requires a change in energy, corresponding to the difference in energy between the two orbits. If an electron moves to a lower energy level, it emits the excess energy; if it moves to a higher level, it must absorb energy.

The orbits closer to the nucleus represent lower energy levels, and those further away have successively higher energy levels. The accuracy of the statement that lower energy levels are closer to the nucleus and higher energy levels are farther from the nucleus is confirmed by Bohr's theory.
