Interpretation:
A time line needs to be made summarizing the major events led to the understanding of alpha, beta and gamma radiation.
Concept introduction:
Radiation is defined as the emission of energy through a space and material in the form of wave or particles.

Explanation of Solution
Ernest Rutherford worked with radiation in the year after 1903 and before 1937. The three types of radiations are identified by him making use of charged plates in order to deflect the emission from radioactive sample. The three types of radiation are alpha, beta and gamma with charges +2, -1 and 0 respectively.
Here, alpha particles are positively charged helium ions. The symbol used to represent alpha particles is
The gamma radiations are high energy radiations with zero charge. The high energy is due to the fact that it consists of shortest wavelength of

- 6. Chlorine dioxide (CIO) is used as a disinfectant in municipal water-treatment plants. It decomposes in a first-order reaction with a rate constant of 14 s. How long would it take for an initial concentration of 0.06 M to decrease to 0.02 M? [6 pts]arrow_forwardIf possible, replace an H atom on the a carbon of the molecule in the drawing area with a methyl group substituent, and replace an H atom on the ẞ carbon with a hydroxyl group substituent. If one of the substituents can't be added for any reason, just don't add it. If neither substituent can be added, check the box under the drawing area. en HO OHarrow_forwardCurved arrows are used to illustrate the flow of electrons.
