A chemist called Dmitri Mendeleev created the best way of arranging all the chemical elements- the modern Periodic Table. He arranged the elements based on their groups, e.g group 1 = alkali metals etc. Protons and nuclei hadn't been observed in his day, so any estimations and predicted elements needed to be clarified in the future. Mendeleev's predictions were accurate- hence his legendary table still exists today. I just hope I've spelt his name correctly!
Dmitri Mendeleev is credited with creating the periodic table, a method for arranging elements based on their properties and atomic number. This arrangement allows for predicting the properties of elements that had not yet been discovered at the time.

This extremely important discovery was made by Russian chemist Dmitry Mendeleyev somewhere in the late 1800's. He suggested arranging the known elements by atomic weight (or mass) - which would, by extension, mean by atomic number - in order to predict the properties of as yet undiscovered elements. His system worked perfectly and enabled other scientists to fill in the blanks and complete what is known as the Periodic Table of Elements.
The four critical elements of planning scenarios are context, trends and uncertainties, alternative futures, and potential implications. These elements help organizations anticipate and prepare for possible future challenges and opportunities.
