The Periodic Table of the Elements
He also created the way the periodic table looks like. He put them into rows called Periods, and columns called groups.
The 3 main catagories are metals, nonmetals, and metalloids (properties of metals and nonmetals)
The periodic table labeled
*Alkali metal *metalloid*alkali-earth metal *non-metals
*transition metal *halogens*noble gases*lanthanide*actinide
Dimitri's 1st periodic table
Before the present day periodic table, this periodic table was organized by Mendeleev, and it was confusing.
Modern day periodic table
Now the periodic table is more easier to read and more organized.
Mendeleev's Periodic Table
The Periodic Table:
- lists each element in order of their atomic number
- elements with similar properties fall in the same column
- put into groups and periods
The periodic table has alkali metals, alkali-earth metals, transition metals, halogens, and noble gases.
