Interpretation: The top ten elements in the human body that are also top ten elements in the earth's crust, ocean, and atmosphere needs to be determined.
Concept Introduction: Every matter is made of chemicals; the importance of chemistry is that it's the study of everything. Chemistry is all about how something interacts to affect the structure, composition, as well as knowing properties of substances.

Answer to Problem 2RQ
The name of elements: Oxygen, Hydrogen, Calcium, magnesium, Potassium, Sodium.
Explanation of Solution
A substance which is made from one type of atom, called element.Chemical elements may be considered as a basic chemical structure blocks of matter. The chemical elements are essential in our daily lives and the most important element is carbon. There are six of the Top Ten elements that are in human bodies as well as the earth’s crust. These elements are mentioned below:
- Oxygen,
- Calcium,
- Magnesium,
- Hydrogen,
- Sodium, and
- Potassium.
An element is described by the figure of protons in the nuclei of its atoms.
