All elements with atomic numbers 1 through 94 occur naturally at least in trace quantities, but the following elements are often produced through synthesis. Technetium, promethium, astatine, neptunium, and plutonium were discovered through synthesis before being found in nature.

Metal – This is a chemical element made up of various opaque, fusible, ductile and lustrous substances, with some of the most commonly used metals being titanium, copper and nickel. Steel – By contrast the metal, this is an alloy of iron that contains various amount of carbon content.

A man-made habitat refers to an environment manufactured or created by human beings, which contains the elements, sometimes synthetic, which would otherwise be found in a natural habitat, and are necessary to support a species.

From the mightiest blue whale to the most miniscule paramecium, life as we know it takes dramatically different forms. Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS). Why those elements?

By mass, about 96 percent of our bodies are made of four key elements: oxygen (65 percent), carbon (18.5 percent), hydrogen (9.5 percent) and nitrogen (3.3 percent). These elements do not give color to fireworks, but they are found in our body's most abundant and important molecules, including water, proteins and DNA.
