9.17.00 1:37 PM6 3.3 Periodic Table
Johann Dobereiner
1780 - 1849
Model of triads
Dia membuat kelompok unsur-unsur terdiri dari 3 unsur yang mempunyai sifat sama , kelompok tersebut disebut Triade
Anggota triade yang di tengah mempunyai sifat-sifat di antara anggota triade yang lain

John Newlands
1838 - 1898
Law of Octaves
Dia menyusun unsur-unsur berdasarkan kenaikan massa atom relatifnya. Ternyata unsur-unsur yang berselisih 1 oktaf ( unsur nomor 1 dengan nomor 8, nomor 2 dengan nomor 9, dan seterusnya ) menunjukkan kemiripan sifat.
9.17.00 1:37 PM8 3.3 Periodic Table
Mendeleev
Unsur-unsur disusun berdasar kenaikan massa atomnya. Unsur-unsur yang sifatnya mirip diletakkan segolongan.
Moseley (Menyempurnakan)
Unsur-unsur disusun berdasar kenaikan nomor atomnya (=jumlah protonnya)

Across the Periodic Table
Periods: Are arranged horizontally across the periodic table (rows 1-7)
These elements have the same number of shells.1IA

Down the Periodic Table
Group : Are arranged vertically down the periodic table (columns or group, 1- 18 or 1-8 A,B)These elements have the same number electrons in the outer most shells (the valence electron).
