Very First Periodic Table

Dimitri Mendeleev - Designed the first periodic table. He put elements in groups by similar properties and then placed them in order by increasing mass. 

Henry Mosely

• Came up with the current periodic table format

• Elements are still grouped by properties

Who Am I?????

Using the notes, clues, and a periodic table determine "who" each of the unknown elements are. When typing in an elemet use the atomic symbol, if it is a family use the full name that was provided in todays notes.
