How to Organize…
Baseball Cards:
year, team, player, card number, value ($).
Elements:
when they weremass,
discovered,
family, reactivity,
alphabetically,
value, density,
state or
of liquid
matter,ormetal
solid
gas vs. non-metal, atomic mass,
atomic number.
Which way is CORRECT to organize the elements?
Is it possible to organize the elements correctly in more than one way?

Development of Periodic Table
J.W. Döbereiner (1829)
Law of Triads
Elements could be classified into groups of three, or triads.
Trends in physical properties such as density, melting point,
and atomic mass were observed.
J.A.R. Newlands (1864)
Law of Octaves
Arranged the 62 known elements into groups of seven
according to increasing atomic mass.
He proposed that an eighth element would then repeat the
properties of the first element in the previous group.
Lothar Meyer (1830 – 1895)
Invented periodic table independently of Mendeleev
his work was not published until 1870 - one year after Mendeleev's
