Interpretation: A table for each type of radiation affecting the
Concept introduction: The number of protons in an atom identifies it as an atom of a particular element because it is equal to the atomic number of the element.
Mass number is referred to as the total number of protons and neutrons in a nucleus.
Radiation is the rays and particles emitted by the radioactive material.
Answer to Problem 29SSC
Particle | Mass number | |
-2 | -4 | |
+1 | No charge | |
No charge | No charge |
Explanation of Solution
Particle | Atomic number | Mass number |
-2 | -4 | |
+1 | No charge | |
No charge | No charge |
Alpha radiation: An alpha particle is emitted in this nuclear disintegration. It occurs with
The mass number in alpha decay is 4 and the atomic number is 2.
An example of alpha decay is given below:
Beta radiation: Beta particle decay is also known as beta ray or beta radiation. It is a high-speed, high-energy electron or positron. The electron or positron is emitted by the radioactive decay of an atomic nucleus during the process of beta decay.
Gamma radiation: A gamma decay is a penetrating
