The Periodic Table

This shows the arrangement or grouping of elements in order of increasing atomic number.

 

The Periodic Law

This is the basic assumption behind the modern periodic table; it states that the properties of the elements are the periodic function of their atomic number.  

 

Electronic Configuration of the First Thirty Elements

The electronic configuration  of an atom is the representation of the arrangement of the electrons distributed among the orbital shells and subshells. Commonly, the electronic configuration is used to describe the orbitals of an atom in its ground state.

Meaning of Atomic Orbital

Orbital is the region of space around the nucleus where there is a high probability of finding electron.
