Apart from oxygen, these elements are not found as 'pure' elements. Instead, they are found either dissolved in water in an ionic form, such as sodium ions and chloride ions, or as parts of large molecules, such as haemoglobin.
Scientists believe that about 25 of the known elements are essential to life. Just four of these - carbon (C), oxygen (O), hydrogen (H) and nitrogen (N) - make up about 96% of the human body.
These four elements are found in the basic structure of all biochemical molecules. For example, glucose is a carbohydrate and its molecular formula is C6H12O6 - each molecule of glucose is made up of 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.
he body has about 75 mg of copper, about one-third of which is found in the muscles. Copper combines with certain proteins to produce enzymes that act as catalysts to help a number of body functions. Some are involved in the transformation of melanin for pigmentation of the skin, and others help to form cross-links in collagen and elastin and thereby maintain and repair connective tissues. This is especially important for the heart and arteries. Research suggests that copper deficiency is one factor leading to an increased risk of developing coronary Heart disease.

What are two elements needed by living things in trace amounts?
Two elements needed by living things in trace amounts are iron and zinc. Iron is essential for oxygen transport in the blood and zinc plays a role in various cellular functions including immune system support and wound healing.
Which element is not a pure element?
Steel is not a pure element, as it is an alloy composed primarily of iron with small amounts of carbon and other elements.
Which element is the mostly deadly poison?
Polonium-210 is considered one of the most deadly poisons to humans. It is a rare and highly radioactive element that can be lethal even in very small amounts due to its intense radioactivity.istrofa.WebServlet@author

Do humans have metal in their bodies?
Yes, humans can have small amounts of metal in their bodies, such as iron in the blood and trace amounts of other metals from the environment.
What is the difference in a compound and an element?
A compound is a combination of more than one element. (In an "element", all atoms - except perhaps for small amounts of impurities - have the same number of protons.)A compound is a combination of more than one element.
