Introduction
Great explanation of the differences between physical and chemical properties and reactions in chemistry and the characteristics that make elements different from compounds. It is also very informative that you provided examples of elements and compounds in the human body and their functions.
Discussion
In the human body, elements like oxygen, hydrogen, and nitrogen are found in the air we breathe (Davey, 2021). Compounds like glucose, proteins, and lipids are essential for the body’s functioning. According to Davey (2021), glucose is the body’s main source of energy, proteins are made up of amino acids and are essential for the growth, development, and repair of body tissues, and lipids are used to store energy and provide essential fatty acids for the body. I agree with your explanation of the use of isotopes in medicine, particularly in diagnosing and treating illnesses. From my personal experience, I have read in many medical journals that isotopes such as Technetium-99m are commonly used in nuclear medicine imaging because of their short half-life and relatively low energy gamma emission (Davies, 2020). It is used to identify areas of inflammation, infection, or cancer in the body.
Conclusion
In conclusion, isotopes can also be used to treat certain medical conditions, such as thyroid cancer, by administering radioactive iodine-131, which targets and destroys cancer cells in the thyroid (Davies, 2020). Can you share more about the safety and potential side effects of using isotopes in medicine? What measures are taken to ensure the safe handling and disposal of isotopes used in medical treatments? I would also like to know about any recent developments in the use of isotopes in medicine and potential future applications.
