Used in a sentence: Ammonia is made of the elements nitrogen and hydrogen.Real-life examples: The substances we know as carbon, oxygen, nitrogen, calcium, and gold are examples of elements.We can split water into hydrogen and oxygen, but we cannot use chemistry to split oxygen or hydrogen into anything else. For example, water (H2O) is made of the elements hydrogen and oxygen. The study and measuring of elements is one of the central focuses of the scientific field of chemistry. If you have taken a chemistry class, you’ve likely seen the periodic table, which displays all the known chemical elements.
