Classification: Alkali Metal – group 1 of the periodic table and are reactive metals due to 1 electron in their outer shell. The alkali metals are malleable, ductile and are good
conductors of heat and electricity.
I learned from this project that all metals are linked together in some way by the periodic table. I found out that they are connected by the time that they were discovered and by the same scientist.
