Chapter 8: Periodic Properties of the Elements
Given information
Elements are given to determine the difference in the order of atomic radii and ionization potential.
Step-by-step explanation
The atomic radius of the elements decreases on going from left to right in the periodic table due to the addition of one electron in the same shell which increases effective nuclear charge and increases on going down the group due to the addition of one shell.
The ionization energy is the energy required to remove the electron from the isolated gaseous atom. This depends upon the electronic configuration of the elements. The elements having fully filled electronic configuration has higher ionization energy as compared to the elements which have incompletely filled orbitals. The ionization energy decreases as the size of the element increases.
