How can isotopes be used in medicine (be specific)?

Discussion Question 1

Using the South University Online Library or the Internet, research elements and compounds. On the basis of your research, respond to the following:

• What are the differences between physical and chemical properties in chemistry?
• What are the differences between physical and chemical reactions in chemistry?
• What are the characteristics that make elements different from compounds? Give two examples of each that exist in the human body and explain their function.

 Discussion Question 2

Using the South University Online Library or the Internet, research any one element. On the basis of your research, provide:

• What are isotopes and how are isotopes distinguished from one another?
• How can isotopes be used in medicine (be specific)? Describe in detail one example of how an isotope is used therapeutically, and describe another example of how an isotope is used diagnostically in medicine.

Sample Solution

Discussion Question 1:

Physical properties are those that can be observed or measured without changing the identity of the substance, such as density, melting point, color, and solubility. Chemical properties, on the other hand, describe how a substance interacts with other substances to form new ones, such as reactivity, combustibility, and acidity.

Physical reactions involve changes in the physical properties of a substance without changing its identity, such as changes in state, shape, or size. Chemical reactions, on the other hand, involve the breaking and forming of chemical bonds between atoms to form new substances with different chemical properties.

Elements are substances made up of only one type of atom, while compounds are substances made up of two or more different types of atoms bonded together chemically. Elements cannot be broken down into simpler substances by chemical means, while compounds can be broken down into their constituent elements by chemical means.

Two examples of elements in the human body are carbon and calcium. Carbon is a crucial component of organic molecules such as proteins, lipids, and carbohydrates, while calcium is important for bone health and muscle contraction. Two examples of compounds in the human body are water and glucose. Water is essential for many bodily functions, such as regulating body temperature, transporting nutrients, and removing waste products. Glucose is a simple sugar that is used as an energy source by the body’s cells.

Discussion Question 2:

Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei, resulting in different atomic masses. Isotopes can be distinguished from one another by their mass numbers, which are the sum of the number of protons and neutrons in the nucleus.

Isotopes can be used in medicine for both diagnostic and therapeutic purposes. One example of therapeutic use is in radiation therapy for cancer. Radiation therapy uses high-energy radiation to kill cancer cells by damaging their DNA. Radioactive isotopes, such as cobalt-60 and cesium-137, are used as a source of radiation in these treatments.

One example of diagnostic use is in PET (positron emission tomography) scans. PET scans use a radioactive isotope, typically fluorine-18, which is attached to a glucose molecule to create a radiotracer. The radiotracer is injected into the patient, where it is taken up by cells that are metabolically active, such as cancer cells. The radiotracer emits positrons, which collide with electrons in the patient’s tissues and produce gamma rays. These …NEED A COMPREHENSIVE ANSWER? POST YOUR ORDER
