Concepts and reason
The concepts used to solve this problem are alpha, beta and gamma symbols and alpha, beta and gamma radiation properties.
First, find the symbols for alpha, beta, and gamma particles.
Finally, use the properties of alpha, beta, and gamma radiation to find what contains a negative charge when the radiation occurs, which radiation is pure energy, and which is the most massive.
Fundamentals
Three emissions occurred during radioactive decay. To identify the particles, they are called alpha, beta and gamma.
Atomic mass is the weight of the atom. It is represented by . Atomic mass is always present by exposing elements.
The number of protons in the nucleus of an atom is defined as the atomic number of a chemical element. He is depicted as. The atomic number is always present in the element index.
The properties of alpha particles are given below:
The nature of alpha rays is that they are positively charged particles. They are also: very active, with high ionizing power, very massive, of stable configuration and easily deflected by electric and magnetic fields.
The properties of beta particles are given below:
High energy and fast electrons, beta particles are negatively charged particles and less massive than alpha particles. These particles are deflected towards the positive plate due to the negative charge.
The properties of gamma particles are as follows:
Gamma rays are electromagnetic radiation. He has high energy. The speed of the gamma ray is similar to the speed of light. It has no cost. It is not deflected by electric and magnetic fields.
Step by step
Step 1 of 6
(1)
The symbol of an alpha particle is given below:
Here, the symbol of the alpha particle is , the atomic mass number is in superscript, and the atomic number is in subscript 4.
Part 1
Thus, the symbol for the alpha particle is .
The alpha particle contains no electrons and is made up of 2 neutrons and 2 protons. The particle has a positive charge and will not have the ability to penetrate most substances.
Do not conclude that the alpha particle has a negative charge; the correct conclusion is that the alpha particle has a positive charge.
Use the emission in natural radioactive decay to find the beta particle symbol.
Step 2 of 6
(of them)
The symbol of beta particle is given below:
Here, the beta symbol is , the mass number is in superscript, and the atomic number is in subscript.
Part 2
Thus, the symbol for the beta particle is .
The beta particle contains will not represent a negative number of protons. It is also less massive than the alpha particle.
Do not conclude that beta particles contain a negative number of protons. The correct conclusion is that beta particles will not contain a negative number.
Use emission in natural radioactive decay to find the symbol for a gamma particle.
Step 3 of 6
(3)
The symbol of the gamma particle is:
Here, the gamma symbol is , the atomic mass number is in superscript and the atomic number is in subscript.
part 3
Thus, the symbol for the gamma particle is .
Gamma rays occur during alpha and beta decay emission. It has properties similar to those of light. The electrons it contains will be in the most stable orbitals.
Do not conclude that gamma rays do not occur due to alpha and beta decay emission. The correct inference is that the gamma ray occurs during alpha and beta decay emission.
Use the alpha, beta, and gamma decay properties to find the correct option that contains a negative charge when radiation occurs.
Step 4 of 6
(4)
Alpha radiation contains positive charges. So the alpha option is the wrong answer.
Gamma radiation has no charge. So the gamma option is an incorrect answer.
Beta radiation contains negative charges. So the beta option is the right answer.
part 4
So, the particle that contains a negative charge when the radiation occurs is beta.
Beta radiation has higher kinetic energy electrons. The charge on the beta particle leaves its place only when the proton transforms into a neutron in the nucleus.
Do not conclude that the beta particle has no electrons. The correct conclusion is that beta particles have electrons.
Use the alpha, beta, and gamma decay properties to find the correct option where the radiation is pure energy.
Step 5 of 6
(5)
Alpha and beta particles are discrete subatomic particles. The emission of alpha and beta particles causes the atomic numbers to change. Therefore, the alpha and beta options are incorrect.
Gamma particles do not change atomic number due to emission. It is the pure energy form of electromagnetic radiation. Therefore, the gamma option is the correct option.
part 5
Thus, the particle whose radiation has pure energy is gamma.
Gamma particles are not deflected by less dense matter. Alpha and beta particles are deflected by less dense matter.
Do not conclude that gamma particles are deflected by less dense matter. The correct conclusion is that gamma particles are not deflected by less dense matter.
Use the alpha, beta, and gamma decay properties to find the correct option that contains the most massive particles.
Step 6 of 6
(6)
Beta and gamma particles do not have a stable particle configuration. Therefore, beta and gamma options are incorrect.
The alpha particle has two protons and two neutrons. It also has a stable configuration. The alpha option is therefore the correct answer.
part 6
So, the particle that has the most massive particles is alpha.
If the particle does not need to lose or gain electrons, it is said to have a stable configuration.
Do not conclude that the alpha particle does not have a stable configuration. The correct conclusion is that alpha particles have a stable configuration.
