An '''element''' is a material that is composed of only one type of [[atom]].  Each different element has a different periodic number, which is the number of [[protons]] in its [[nucleus]].<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref> [[Hydrogen]] has only one proton whereas [[uranium]] has 92. Uranium is the largest of the stable elements occurring in nature.  All of the elements are listed on the [[periodic table of the elements|periodic table]] with the heavier ones produced in a laboratory. These elements (or [[compounds]] made from these elements) make up all matter on the earth and quite possibly all matter outside of the earth as well.

An '''element''' is a single type of [[atom]] as defined by its [[atomic number]], which is the number of [[protons]] in its [[nucleus]].<ref>Wile, Dr. Jay L. ''Exploring Creation With Physical Science''. Apologia Educational Ministries, Inc. 1999, 2000</ref> In contrast, a single element may have varying [[mass number]]s, relating to the number of neutrons in its nucleus.

 

The element [[hydrogen]] has only one proton whereas the element [[uranium]] has 92, and there are elements with even more protons than that. However, uranium is the largest naturally occurring element in nature.   

 

All known elements are listed on the [[periodic table]], with the ones with more protons than uranium produced in a laboratory. Joining atoms of the same or different elements produces chemical [[compound]]s. The elements and their compounds make up all matter on the earth and quite possibly all matter outside of the earth as well.
