Complete the sentence: Based upon the Bohr model of the atom, electrons__________.
The options are:
a) can exist at any distance from the nucleus
b) travel in pathways called orbitals
c) possess quantized energy
d) travel as waves
e) answers b & c are correct
e) answers b & c are correct
To complete the sentence, we need to determine what characteristics of electrons are based on the Bohr model of the atom. The Bohr model suggests that electrons exist in specific energy levels or shells around the nucleus. With this understanding, let's evaluate the options:
a) Can exist at any distance from the nucleus: This option is incorrect. The Bohr model suggests that electrons occupy specific energy levels and cannot exist at any distance from the nucleus.
b) Travel in pathways called orbitals: This option is correct. According to the Bohr model, electrons move in well-defined circular orbits around the nucleus.
c) Possess quantized energy: This option is correct. The Bohr model describes electrons having precise energy levels that are specific to each shell, and energy changes occur when electrons transition between these levels.
d) Travel as waves: This option is incorrect. Although the wave-particle duality principle is true for electrons in quantum mechanics, it is not a specific characteristic of the Bohr model.
e) Answers b & c are correct: This option is correct. By analyzing the previous explanations, we can conclude that both options b and c are characteristics of electrons based on the Bohr model.
Therefore, the correct completion of the sentence is: "Based upon the Bohr model of the atom, electrons travel in pathways called orbitals and possess quantized energy."
