It was first prepared in pure form in 1807 by English chemist Sir Humphry Davy (1778-1829).Davy used a new method of isolating elements that he had invented, electrolysis. The alkali metals are the elements that make up Group 1 (IA) of the periodic table.The periodic table is a chart that shows how chemical elements are related to one another.As the air warms, different elements change from a liquid back to a gas.
It was the first of the noble gases to be isolated.This is because both the protons and the neutrons in an atom have a relatively equal mass.The mass of an electron is so insignificant that it is not represented in the atomic mass.In electrolysis, an electric current is passed through a molten (melted) compound.The electrical current breaks the compound into its elements.
In this case, however, it would be possible to find out how fast the water moves into any one part of the plant.
