Who created the periodic table and how is it organized?
Metalloids
Alkali Metals
Sum of Protons and Neutrons (Nucleus)
Nobel Gases
Dimitri Mendeleev; atomic weight
Rare Earth Metals (lanthanides and actinides)
Periodic Table
# of Protons and # of Electrons
Group where many elements are man-made and named after scientists. hint: spurs from transition metals
