Physics Topic 7: Atomic And Nuclear Physics

1. What is one limitation of the simple model of the nuclear atom?

The model effectively demonstrates how atoms achieve stability through electron configuration.

The model accurately represents isotopes and different atomic weights, making it a comprehensive model of the nuclear atom.

Limitations include: the model does not take intoconsideration isotopes and different atomic weights, and the model does notshow how the atom would be stable. Electrons would lose energy with radiation.

The model accounts for all forms of radiation, ensuring that electrons do not lose energy in the process.

The simple model of the nuclear atom has limitations such as not considering isotopes, different atomic weights, and the stability of the atom. It also does not address how electrons lose energy through radiation.

2. Explain the terms nuclide, isotope, and nucleon.

C. Nuclide: A certain configuration of protons and electrons. Isotope: Atoms with the same number of protons but different number of electrons. Nucleon: A type of photon.

Nuclide: A particular type (species) of nucleus with a certain number ofprotons and neutrons. Isotope: Nuclei with the same number of protons (Z) but different number ofneutrons (N) e.g. C-12 and C-14. Nucleon: A proton or neutron (not necessarily a particles within nucleus).

B. Nuclide: A specific type of electron configuration. Isotope: Nuclei with the same number of protons and electrons. Nucleon: A particle outside of the nucleus.

A. Nuclide: A type of atom with different number of electrons. Isotope: Nuclei with the same number of neutrons and protons. Nucleon: A type of electron.

A nuclide is specifically related to the nucleus, while a nucleon refers to protons and neutrons. Isotopes have the same number of protons but different number of neutrons.

Explanation

A nuclide is specifically related to the nucleus, while a nucleon refers to protons and neutrons. Isotopes have the same number of protons but different number of neutrons.

3. Define nucleon number A, proton number Z, and neutron number N.

Nucleon Number: Number of nucleons (Protons + Neutrons) inthe nucleus. Also known as mass number. Symbol is A. Proton Number: Number of protons in the nucleus . Alsoknown as atomic number. Symbol is Z. Neutron Number: Number of neutrons in the nucleus. Symbolis N. N=A-Z

4. 7.2.2: Describe the properties of alpha and beta particles and gamma radiation

Refer to image

Alpha particles are negatively charged, beta particles are positively charged, and gamma radiation is composed of protons and neutrons

Alpha particles have the highest penetrating power, beta particles have the lowest penetrating power, and gamma radiation is a form of electromagnetic radiation

Alpha particles are the most ionizing, beta particles are the least ionizing, and gamma radiation is made up of electrons

The properties of alpha and beta particles and gamma radiation are distinct and are not as described in the incorrect answers. The correct properties are best referenced in the available image.

Explanation

The properties of alpha and beta particles and gamma radiation are distinct and are not as described in the incorrect answers. The correct properties are best referenced in the available image.

5. 7.3.6: Draw and annotate a graph showing the variation with nucleon number of the binding energy per nucleon.

Include the variation of electron number in the graph.

Graph not required.

Refer to image

Plot the variation of atomic number instead of nucleon number.
