Interpretation:
The different types of radiation and their changes need to be explained.
Concept introduction:
Isotopes are atoms of same element whose number of neutrons is different. Isotopes having unstable nuclei are termed as radioisotopes. These unstable nuclei emit radiation to attain more stable atomic configuration is termed as radioactive decay.

Answer to Problem 1SSC
Three types of radiation, that is, alpha, beta and gamma.
Explanation of Solution
During radioactive decay, unstable atoms lose energy due to emission of radiation. Three types of radiation which are common are alpha
Alpha particle
Beta particle is a very fast moving electron which is emitted when a neutron is unstable nucleus converted into a proton. This particle is represented by
Gamma rays are photons, which are high-energy electromagnetic radiation. They are represented by the symbol
Three type of radiations, alpha

One example is Compound C shown below, which could be imagined as adopting four possible conformations. In reality, however, only one of these is particularly stable. Circle the conformation you expect to be the most stable, and provide an explanation to justify your choice. For your explanation to be both convincing and correct, it must contain not only words, but also "cartoon" orbital drawings contrasting the four structures.
