Question Which incorrect aspect of Rutherford’s model was fixed by Bohr’s model?(1 point) Responses The nucleus contains most of the mass of an atom. The nucleus contains most of the mass of an atom. Atoms have small, dense, positively charged nuclei. Atoms have small, dense, positively charged nuclei. Positively charged nuclei repel positively charged alpha particles. Positively charged nuclei repel positively charged alpha particles. Electrons move freely in curved paths around the nucleus.

Answer 1

The incorrect aspect of Rutherford’s model that was fixed by Bohr’s model is:

Electrons move freely in curved paths around the nucleus.

Bohr's model introduced the concept of quantized energy levels for electrons, meaning that electrons can only occupy specific orbits or energy levels around the nucleus, rather than moving freely in any path.

Answer 2

You plan to pass alpha particles through a field that contains a consistent type of particle. Which configuration will result in the largest deflection of alpha particles? (1 point) Responses low-energy alpha particles passing through a field of low mass-number-particles low-energy alpha particles passing through a field of low mass-number-particles high-energy alpha particles passing through a field of high mass-number-particles high-energy alpha particles passing through a field of high mass-number-particles high-energy alpha particles passing through a field of low mass-number-particles high-energy alpha particles passing through a field of low mass-number-particles low-energy alpha particles passing through a field of high mass-number-particles

Answer 3

The configuration that will result in the largest deflection of alpha particles is:

High-energy alpha particles passing through a field of low mass-number particles.

High-energy alpha particles have greater kinetic energy and therefore can have more significant interactions with lighter (low mass-number) particles, leading to larger deflections. The lighter particles will be less massive and thus more easily moved by the momentum of the high-energy alpha particles, resulting in a greater change in direction.

Answer 4

Question Which statement about metals and nonmetals is correct?(1 point) Responses Metals can be hammered into thin sheets, and nonmetals are brittle. Metals can be hammered into thin sheets, and nonmetals are brittle. Metals and nonmetals can both be found in any column of the periodic table. Metals and nonmetals can both be found in any column of the periodic table. Most metals are a solid under normal conditions, and most nonmetals are a liquid. Most metals are a solid under normal conditions, and most nonmetals are a liquid. Metals tend to be poor conductors of electricity, while nonmetals are strong conductors of electricity.

Answer 5

The correct statement about metals and nonmetals is:

Metals can be hammered into thin sheets, and nonmetals are brittle.

This statement accurately reflects the properties of metals, which are malleable (can be shaped into thin sheets), and nonmetals, which tend to be brittle when solid. The other statements contain inaccuracies regarding the properties of metals and nonmetals.
