Mendeleleev
developed of the first Periodic Table
NAME
Vertical columns were arranged in order of increasing atomic - mass
vertical columns placed side by side formed horizontal rows with similar
properties
In 1875, His table predicted the properties of the element Gallium
-Modern Periodic Table was developed by Henry Mosley
based on increasing
Atomic number
7 Periods or Horizontal rows
Families or Groups are Vertical columns have similar Physical & Chemical properties
Periodic Law when elements are arranged by increasing atomic number,
there is a periodic repetition of their physical & chemical properties
There are 4 categories
of elements
