who discover periodic table
Mosley (for Modern Periodic table)
Drawback: Hydrogen could not be placed in periodic table.
yeah but which periodic table r u askin abt????
hey wat about mandleev????
Mendeleev arranged his p.t in increasing order of atomis mass!!!!!!!!!
Mendeleev was awarded for making a periodic table based on atomic masses. He was the first scientist to actually properly arrange elements according to their chemical properties. The periodic law goes like "Elements are the periodic functions of the atomic masses " (1 marker asked in CBSE 2009).
He predicted the properties of those elements that were not discovered like germanium, scanidium etc and they were correct. But certain problems still pertained after the creation of Mendeleev 's periodic table. Thats when Henry Moseley 's Periodic Table came into rounds.
Dobereiner for traids
newlands for his octaves
mendeleev for his mendeleev 's periodic talbe
mosely for his modern periodic table
now, modifications are still on the way, so we are now using the table made by group of chemists, still they are making the modifications.
hope you must have understood, if yes, please give thumbs up.
yes it is henry mosley
Henry Mosley discovered the modern periodic Table
There are many others who grouped elements in the form of table
They are Mendeleev, John Dalton, Newland, Dobereiner.
But their Classifications are discarded
