Question

Radon is used in decorative lights. True or False.

Answer 1

Hint: You may begin by explaining what radon is. You could then mention all the properties of this element and also check for some property that has a chance for it being used in decorative lights. Then, you could check whether the given statement is true or false. If false, give the element that is actually used in decorative lights.

Complete step-by-step solution:
In the question, we are given a statement and we are supposed to find whether it is true or false. Let us first talk about radon. Radon is one of the chemical elements that is represented by the symbol Rn with an atomic number 86. It falls under the group of noble gases and it is known to be radioactive, colorless, odorless as well as tasteless. It is also an immediate decay product of radium. Its most stable isotope is known to have a half life of 3.8days or so. Hence, it is known to be one among the rare elements. The discovery of this element was done by Friedrich Ernst Dorn.
Now let us discuss the uses of this element. The decay of radon leads to the production of radioactive polonium and alpha particles and radiation that is emitted during this decay is used for cancer therapy. It is also known to have a significant role in the process of evolution.
Now, it is actually Neon that is used in decorative lights not radon. Hence, the given statement is proved false.

Note: We have discussed the medical significance of radon in cancer therapy. However, precautions are taken while dealing with radon in hospitals. These gases are sealed in minute tubes and then implanted to tumour and thereby treating the disease. Now, we have other treatments which are far safer than this.
