Periodic Table

Electronic Configuration of D-Block Elements: In the transition elements, d-orbitals of penultimate shell are successively filled. The first transition series involves the filling of 3d…

Ionization energy is dependent on the electronic configuration of an element. For this reason, there are some deviations in the gradual increase of ionization potential…

Ionization potential is a periodic property. Generally in a group with the increase of atomic number the ionization potential of elements decreases from top to…

The amount of energy required to remove the most loosely held electron from a neutral gaseous atom of an element in its ground state to…

Inert gas The zero group consists of six elements: Helium (2He), Neon (1oNe), Argon (18Ar), Krypton (36Kr), Xenon (54Xe) and Radon (86Rn). They are all inactive…

The modern periodic law states that, “The physical and chemical properties of the elements and their compounds are periodic functions of their atomic number.” In…

Mendeleev’s periodic law states that “The physical and chemical properties of elements and their compounds are periodic functions of their atomic mass.” Mendeleev arranged 63…

Both nitrogen and phosphorous are placed in group VA as they some similarities between them which are discussed below: 1. Electronic Structure: N and P…
