About This Quiz

The '3.1 Quiz - Nuclear Emissions' assesses understanding of nuclear stability and decay types, focusing on properties and effects of alpha, beta, and gamma emissions. It's crucial for learners studying nuclear physics, providing insights into fundamental atomic behaviors.

2.

Which nuclear decay has the greatest penetrating power and the least mass?
- Alpha
- Beta
- Gamma
- Positron
Correct Answer

A. Gamma

Explanation

Gamma radiation has the greatest penetrating power (remember: alpha, beta, gamma), but the least mass (0 amu, top number on Table O).

Rate this question:
3.

Which nuclear emission has the most mass and least penetrating power?
- Gamma radiation
- Alpha particles
- Beta particles
- Positrons
Correct Answer

A. Alpha particles

Explanation

Alpha particles have the greatest mass of 4 amu (top number on Table O), but the least penetrating power (remember: alphabetical order... Alpha, Beta, Gamma).

Rate this question:
4.

Which nuclear decay consists of helium nuclei?
- Positrons
- Alpha particles
- Beta particles
- Gamma radiation
Correct Answer

A. Alpha particles

Explanation

Alpha particles equal helium nuclei. They have a mass of 4 amu (top number, Table O) and a charge of +2 (bottom number, Table O).

5.

Without looking at a graph, why is O-16 a stable nuclide?
- Because it has a 8:1 ratio of protons to neutrons
- Because it has a 1:1 neutron-to-proton ratio
- Because it has a 1.6:1 neutron-to-proton ratio
- Because it has a 16:8 proton-to-neutron ratio
Correct Answer

A. Because it has a 1:1 neutron-to-proton ratio

Explanation

The number of protons equals atomic number. The number of neutrons equals mass number (16 for O-16) minus atomic number (8 for O-16). The band of stability (range of stabilities for neutron-to-proton ratios) is 1:1-1.5:1. Any nuclide with a neutron-to-proton ratio in this range is stable and will not spontaneously decay.

Rate this question:
6.

Which nuclear decay consists of electrons?
- Positrons
- Gamma particles
- Alpha particles
- Beta particles
Correct Answer

A. Beta particles

Explanation

Beta particles equal electrons. They have a mass of 0 amu (top number, Table O) and a charge of -1 (bottom number, Table O).

Rate this question:
7.

Which nuclear decay consists of energy, only?
- Gamma
- Alpha
- Beta
- Positrons
Correct Answer

A. Gamma

Explanation

Gamma particles are equivalent to energy. They have a mass of 0 amu (top number, Table O) and a charge of 0 (bottom number, Table O).

Rate this question:
8.

Which list correctly ranks nuclear emissions in order of increasing mass?
- Alpha, beta, gamma, positron
- Beta/Gamma/Positron, Alpha
- Beta, Alpha, Gamma, Positron
- Positron, Alpha, Gamma, Beta
Correct Answer

A. Beta/Gamma/Positron, Alpha

Explanation

Beta, Gamma, and Positrons all have a mass of 0 amu (top number on Table O), meaning smallest mass. Alpha particles have the largest mass of 4 amu (top number on Table O).

Rate this question:
9.

Which list correctly organizes nuclear emissions in order of increasing charge?
- Beta, Positron, Gamma, Alpha
- Positron, Beta, Gamma, Alpha
- Beta, Gamma, Positron, Alpha
- Alpha, Beta, Gamma, Positron
Correct Answer

A. Beta, Gamma, Positron, Alpha

Explanation

Beta particles have the smallest charge of -1, Gamma particles have a charge of 0, Positrons have a charge of +1, Alpha particles have a charge of +2 (bottom number, Table O).

Which of the following correctly lists the number of protons, the number of neutrons, the mass number, and the nuclide notation for N on this graph? (ONLY use this graph. Do not look at other references. I want you to test how much you know!!!!)
- 9 protons, 7 neutrons, Mass Number of 16, N-16 for nuclide
- 6 protons, 6 neutrons, Mass Number of 12, C-12 for nuclide
- 16 protons, 16 neutrons, Mass Number of 32, S-32 for nuclide
- 7 protons, 9 neutrons, Mass Number of 16, N-16 for nuclide
Correct Answer

A. 7 protons, 9 neutrons, Mass Number of 16, N-16 for nuclide

Explanation

Number of protons=x-value, number of neutrons=y-value, mass number=protons + neutrons, nuclide=symbol + mass number.
