Periodic Table

The hydrogen bond is electrostatic in nature. The strength of hydrogen bond is generally 20-40 KJ mole-1; while that of ordinary chemical bond is between…

Hybridization is the process of formation of new equivalent orbitals from mixing u of two or more non equivalent atomic radius. The new orbitals are…

All the elements of the d block are transition metals. Transition elements are those elements that have partly or moderately filled d orbital in their…

The magnetic properties of a D-Block Elements are determined by the number of unpaired electrons in it. There are various substances which show magnetic activities.…

All transition elements exhibit variety of oxidation states (or) variable valencies in their compounds. This property is due to the following reasons. i) These elements…

Variation of ionization potential value in a period: Ionization potential of elements is a periodic property. Generally in the periodic table with the increase of…

Atomic Radius of elements change in Periodic Table: Atomic size is a periodic property. In any period as one goes from left to right (i.e., as…

Catalytic Properties: Most of the transition metals and their compounds are used as catalyst. The catalytic activity of transition metals is due to the following reasons.…

Formation of coloured ions of of d-block elements: An electron jumps from one d-orbital to another. Most of the transition metal compounds are colored in…

Atomic and Ionic Radii of D-Block Elements: The atomic and ionic radii of transition elements are smaller than those of ‘p’ block elements and larger…
