a) While going down the group new shell adds thus increasing the size.
b) While going along the period as force of attraction increases between electrons and protons.
c) It increases because of adding a shell and increase in I.E. value.
d) It decrease due to increase in electro negativity.
e) Atomic no. is more fundamental because every element have different atomic no.

narensai:
last e is wrong
what is it then
Atomic number of an element is numerically equal to the number of electrons round the nucleus.
The number of electrons in turn is equal to the number of protons in the nucleus.
Atomic number is a more fundamental property of an element than its atomic mass because when the elements are arranged in the increasing order of their atomic number, most of the defects of Mendeleev's classification get rectified.
