Which type of decay leads to the change:
- A.
Alpha
- B.
Beta
Correct Answer
A. AlpHaExplanation
Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This process leads to the change in the atomic number and mass number of the nucleus. Alpha decay occurs in heavy and unstable nuclei to increase stability by reducing the number of protons and neutrons. Therefore, the correct answer is alpha.Rate this question:

Which type of decay leads to the following change:
- A.
Alpha
- B.
Beta
Correct Answer
B. BetaExplanation
Beta decay is a type of radioactive decay in which a beta particle (either an electron or a positron) is emitted from the nucleus. This leads to a change in the atomic number of the nucleus, as a neutron is converted into a proton or vice versa. In the given question, the change mentioned is "beta", indicating that beta decay is responsible for this type of radioactive decay.Rate this question:

Answer option 3
- D.
Answer option 4
Correct Answer
A. BetaExplanation
The given answer, "beta," refers to a type of decay that leads to the change described in the question. Beta decay occurs when a nucleus emits a beta particle, which can be either an electron or a positron, resulting in the transformation of a neutron into a proton or vice versa. This type of decay is characterized by the emission of high-energy particles and is commonly observed in radioactive isotopes.Rate this question:

- B.
232
- C.

- D.
230
Correct Answer
A. 234Explanation
In beta decay, a neutron is converted into a proton, and a high-energy electron (beta particle) is emitted from the nucleus. The atomic mass number remains the same, as it represents the total number of protons and neutrons in the nucleus. Therefore, the correct answer is 234, as it signifies that the atomic mass number does not change during beta decay.Rate this question:

When writing an equation of beta-decay for , you will change the atomic number to
- A.
90
- B.
92
- C.
88
- D.
91
- E.
89
Correct Answer
D. 91Explanation
In beta decay, a neutron is converted into a proton, resulting in an increase in the atomic number by one. Therefore, when writing an equation of beta decay for an element, the atomic number will be changed to the next higher number. In this case, since the original atomic number is not given, we can assume it to be 90. Thus, the correct answer is 91, as it represents the new atomic number after beta decay.Rate this question:

89
Correct Answer
C. 88Explanation
In alpha decay, an alpha particle (which consists of two protons and two neutrons) is emitted from the nucleus of an atom. This results in the atomic number decreasing by 2 and the mass number decreasing by 4. Therefore, when writing an equation of alpha-decay for an atom with an atomic number of 90, the new atomic number would be 88.Rate this question:

Which radiation has the highest penetrating power?
- A.
Alpha
- B.
Beta
- C.
Gamma
- D.
Answer option 4
Correct Answer
C. GammaExplanation
Gamma radiation has the highest penetrating power compared to alpha and beta radiation. This is because gamma radiation consists of high-energy photons that can easily penetrate matter, including thick barriers and shielding materials. Alpha particles, on the other hand, are relatively large and heavy, causing them to interact more readily with matter, resulting in less penetration. Beta particles, which are high-speed electrons or positrons, have intermediate penetrating power compared to alpha and gamma radiation. Therefore, gamma radiation is the correct answer as it can penetrate the most.Rate this question:

Gamma rays have
- A.
No mass
- B.
A huge mass
- C.
A small mass
- D.
An average mass
Correct Answer
A. No massExplanation
Gamma rays have no mass because they are a form of electromagnetic radiation. Electromagnetic waves, including gamma rays, are composed of photons, which are massless particles. Therefore, gamma rays do not have any mass.Rate this question:

Which radiation has the lowest penetrating power?
- A.
Alpha
- B.
Beta
- C.
Gamma
- D.
Answer option 4
Correct Answer
A. AlpHaExplanation
Alpha radiation has the lowest penetrating power compared to beta and gamma radiation. Alpha particles consist of two protons and two neutrons, making them relatively large and heavy. Due to their size and charge, they interact strongly with matter, causing them to lose energy quickly and have a limited ability to penetrate materials. This is why alpha radiation can be easily stopped by a sheet of paper or a few centimeters of air. In contrast, beta and gamma radiation, which consist of smaller particles or electromagnetic waves, have higher penetrating power and can pass through thicker materials.Rate this question:
-

Gamma rays are
- A.
Rays of particles
- B.
Waves of particles
- C.
Electromagnetic waves
- D.
Visible light rays
Correct Answer
C. Electromagnetic wavesExplanation
Gamma rays are a type of electromagnetic waves. They have the highest frequency and shortest wavelength in the electromagnetic spectrum. They are produced through nuclear reactions, radioactive decay, and high-energy particle interactions. Gamma rays have the ability to penetrate through matter and are used in various fields such as medicine, industry, and research. Therefore, the correct answer is electromagnetic waves.Rate this question:

Examples of gamma rays emitted during an alpha or beta decay are
- A.
Infrared waves
- B.
Radio waves
- C.
X-rays
- D.
Microwaves
Correct Answer
C. X-raysExplanation
During alpha or beta decay, high-energy particles are emitted from the nucleus. Gamma rays are a type of electromagnetic radiation with very high energy and frequency. X-rays, on the other hand, are also a form of electromagnetic radiation but with slightly lower energy compared to gamma rays. Since both gamma rays and X-rays are part of the electromagnetic spectrum, it is possible for gamma rays to be emitted during alpha or beta decay. Therefore, X-rays can be considered as examples of gamma rays emitted during alpha or beta decay.Rate this question:

Isotopes of the same element have a different
- A.
Number of protons
- B.
Number of electrons
- C.
Number of neutrons
- D.
Atomic number
Correct Answer
C. Number of neutronsExplanation
Isotopes of the same element have a different number of neutrons. Isotopes are variants of an element that have the same number of protons and electrons but differ in the number of neutrons. This difference in neutron number results in isotopes having different atomic masses. Therefore, the correct answer is the number of neutrons.Rate this question:

The process in which one nucleus falls apart into two nuclei of smaller masses is called
- A.
Fission
- B.
Fusion
- C.
Explosion
- D.
Atomic bomb
Correct Answer
A. FissionExplanation
Fission is the correct answer because it refers to the process in which one nucleus breaks apart into two nuclei of smaller masses. This process typically occurs in heavy atomic nuclei, such as uranium or plutonium, and releases a large amount of energy. Fission is the basis for nuclear power reactors and atomic bombs, making it a significant concept in the field of nuclear physics.Rate this question:

The process in which two nuclei combine into one is called
- A.
Fission
- B.
Fusion
- C.
Explosion
- D.
Atomic bomb
Correct Answer
B. FusionExplanation
Fusion is the process in which two nuclei combine into one. This occurs when the nuclei are brought close enough together that the strong nuclear force overcomes the electrostatic repulsion between the positively charged protons in the nuclei. Fusion is the process that powers the sun and other stars, as well as hydrogen bombs. It is the opposite of fission, which is the process in which a nucleus splits into two smaller nuclei. Explosion and atomic bomb are not accurate descriptions of the process of two nuclei combining into one.Rate this question:
