Why atomic number as the basis of modern periodic table?
Answers
Answer:
The Modern Periodic Law states, 'Physical and chemical properties of elements are periodic functions of their atomic numbers. ' Since the properties of an element depend on its electronic configuration, thus electronic configuration of elements is intrinsic to the Modern Periodic Table .
Answer:
The periodic table was created for the purpose of systematic study of elements and their properties.The scientist thus wanted to keep the elements in such a way that there are some chemical resemblance in the properties of the elements at a regular interval.
They started making tables arranging elements according to their increasing atomic weight(total no. of neutron and proton in a nucleus of an element).But this did not work out well.So they were not able to make a systematic table for arranging elements.
Later it was found that the chemical properties of an element depends on the no.of electron and their arrangement and not on the total no.of neutron and proton in a nucleus of an element.
So the elements were arranged in increasing order of the atomic number.
This table showed periodicity in elements after regular intervals and became the most accepted table for arrangement of elements.
