The Periodic Table Developed by
" and properties of an element are the periodic function of its atomic number"
This was the basic concept in formation this Known Modern Periodic Table.
The repetition of elements with similar properties after certain intervals, when the elements are arranged in order of increasing atomic number.
The periodic repetition of the properties of the elements is due to the recurrence of similar valence shell electronic configuration after certain regular intervals.
Horizontal row of periodic table consists of elements having same no. of outermost shell.
Vertical Column consists of a series of elements having similar valence electron.
in Periodic Table:
: In a period (while moving from left to right), the no. of valence electron increases from 1-8. There is no change of valency in a group.
size: In a period the atomic radii increases. In a group the atomic radii of elements increases gradually.
and Non-metallic character
In a period ,the metallic character decreases while the non-metallic character increases. On moving down the group the metallic character increases while the nonmetallic character decreases.
