seaborgium, the chemical element of atomic number 106, a very unstable element made by high-energy atomic collisions.
He created the periodic table.
The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
The 3 major divisions on the periodic table are metals(metalloids), non-metals, and gases.
Germany. During the 1800's chemistry belonged to the Germans, especially organic chemistry. France and Britain made major contributions and the periodic table was a Russian development, but overall, Germany did the most.
More subatomic particles, more mass

it is metals

When you move from left to right on the periodic table, the atomic number of the elements increase.
Metals and non metals
As you move left to right on the periodic table, the number of valence electrons an element has increases. The number of valence electrons an element has corresponds to which group (column) an element is. (This rule does not apply to transition metals...)
H on the periodic table represents Hydrogen. This is the lightest element but it is very essential to life because it is a major component to water (H2O).
He created the periodic table.
Many scientists have made major contributions to society. Mendeleev - who created the first periodic table of elemets
metals, non metals, metaloids
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
