Traditionally, early Greeks considered that there were four classical elements: earth, air, fire, and water.. Some Early Ideas About Elements. Later, around 1667, it was thought there was the existence of, in addition to the classical four elements of the Greeks, an additional fire-like element called “. Physical Science 115. 1.

What is a valence electron?. The electrons in the last shell or energy level. These determine how an atom behaves, reactivity, bonding.
