Question

The data provide evidence that ________.

1) the exact locations of electrons can be determined, contrary to the quantum mechanical model
2) the data support all of the ideas in quantum mechanical model, which is the currently accepted model
3) the data prove that the quantum mechanical model is wrong and the bohr model is correct
4) the data provide evidence that electrons are found only at certain energy levels as described by the quantum mechanical model

Answer 1

The data provide evidence that electrons are found only at certain energy levels as described by the quantum mechanical model. The Bohr model explained the experimental data for the hydrogen atom and was widely accepted, but it had limitations in predicting the behavior of larger atoms. Quantum mechanics, the currently accepted model, explains the behavior of electrons with the concept of quantized energies for electrons of all atoms and the organization of electrons within atoms.

Step-by-step explanation:

The data provide evidence that electrons are found only at certain energy levels as described by the quantum mechanical model.

The Bohr model explained the experimental data for the hydrogen atom and was widely accepted. However, it had limitations in predicting the behavior of larger atoms and emission spectra for elements other than hydrogen. Quantum mechanics, the currently accepted model, explains the behavior of electrons with the concept of quantized energies for electrons of all atoms and the organization of electrons within atoms.

In the quantum-mechanical model, the location of electrons in the atom is described by four quantum numbers. The first three quantum numbers identify where electrons are in an atom, and the fourth one describes the electron's spin direction.
