. What do you men by Long form of Periodic Table or Moseley's Periodic Table


Best Answer

Long form of Periodic Table or Moseley's Periodic Table:

i. Moseley (1909) studied the frequency of X-rays produced by the bombardment of a strong beam of electrons on a metal target. He found that the square root of the frequency of X-rays  is directly proportional to the total nuclear charge (Z) of metal. 

ii. Moseley's Periodic Law or Modern Periodic Law: Physical and chemical properties of elements are the periodic functions of their atomic number. If the elements are arranged in order of their increasing atomic number, after a regular interval, element with similar properties are repeated.
