Based on the article "will the real atomic model stand up? ," describe one major change that occurred in the development of the modern atomic model.

Which statements describe Rutherford’s model of the atom? Select all that apply.

The atom is mostly empty space.

The atom cannot be divided into smaller particles.

Electrons orbit around the center of the atom.

The atom’s positive charge is located in the atom’s nucleus.

The electrons are located within the positive material of the nucleus.

Electron clouds are regions where electrons are likely to be found.

Explanation:

Sample Response: The one major change that occurred was the placement and organization of the electron. Rutherford’s model identified that the electrons were at a distance from the nucleus, Bohr’s model identified that the electrons occurred at levels that related to their available energy, and the modern atomic model shows that electrons are located in a predicted area but cannot be identified in a specific point.
