Elements that decay into other elements with a known rate of decay.
oxygen
These elements are H, O, C, N.
Magnetic materials may contain any mixture of certain elements. Three of the most common elements are iron, nickel and cobalt.
Shortly after Earth's formation and early crustal formation, an occurence called 'The Iron Catastrophe' occured, where iron sank to the center of the planet. The heat released from this occurence literally melted the entire planet, and as the iron sank to the center, lighter materials rose, the lightest forming the crust. The density of materials increases with depth. Although uranium and other heavy elements are found in the crust, it is due to their chemical preference to appear as a trace element in the silicate crust than to appear in the core.
All materials and that includes minerals contain the elements. Sulfates contain sulfur and oxygen

C + 2S -> CS2 Enthalpy of formation is the change in enthalpy for the formation of a substance from its elements.
All materials (indeed all things) are made up of atoms of various elements.
Everything in the world is made from elements.
These elements are H, O, C, N.
An absolute complement is the set which includes exactly the elements belonging to the universal set but not to a given set.
The enthalpy of formation of a substance is the amount of energy that was put in or evolved from the making of that substance from the individual elements.
