Physical and Chemical Properties- elements and compounds
Discussion Question 1
As in all assignments, cite your sources in your work and provide references for the citations in APA format. 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
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.

Discussion Question 1What are the differences between physical and chemical properties in chemistry?
Physical properties are characteristics of matter where there is no change in the chemical composition and are the ones we see with the naked eye, such as color, and chemical properties are those that are observed when matter undergoes a change in its composition. Physical properties do not change the structure of matter, while chemistry does. Chemical properties are associated with a chemical reaction, while physical properties do not. Physical properties are directly measurable, while chemical properties are not always measurable.
What are the differences between physical and chemical reactions in chemistry?
The main difference is in a change in the composition of the substance. In a physical reaction, there is a difference in appearance, smell, or matter, but there is no change in composition or transformation into a new substance. In a chemical reaction, there is a change in the composition of the substances, and some are transformed into other different substances, including those with different properties.
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.
An element is a pure chemical substance made of a kind of atom, while a compound atom from different elements that are chemically combined. An element cannot be broken down further...
