What is Dynamic Equilibrium?
Dynamic equilibrium: When a reversible reaction reaches at equilibrium, then it seems to be stopped. Because, in this situation there seems to no change in…
Chemistry
Explain Law of Mass Action
In a particular temperature and time the rate of any reaction is proportional to the activation mass (Molar concentration and partial pressure) of the reactants…
Explain Consequences of Lanthanide Contraction
The atomic size or ionic radii of tri positive lanthanide ions decrease steadily from La to Lu due to increasing nuclear charge and electrons entering…
Cause of Lanthanide Contraction
The Lanthanide Contraction describes the atomic radius trend that the Lanthanide series exhibit. It is a very important phenomenon in determining the characteristics of the…
Explain General Properties of Lanthanides
General properties of Lanthanides Electronic configuration The electronic configuration of Lanthanides is listed in the table. The fourteen electrons are filled in Ce to Lu…
Define Lanthanide Series
The Lanthanide series include fifteen elements i.e. lanthanum (57La) to lutetium (71Lu). Lanthanum and Lutetium have no partly filled 4f- subshell but have electrons in…
Define f-block Elements
Elements whose f orbital getting filled up by electrons are called f block elements. The elements in which the extra electron enters ( n- 2…
Explain the formation and structure of Ethylene (C2 – H4) by SP2 Hybridization
Formation and structure of ethylene molecule: In ethylene and in other organic compounds having C = C bond, 2s and two 2p orbitals of carbon…
Incomplete Octet in Boron Trifluoride (BF3) Molecule
In some compounds like Beryllium Chloride (BeCl2), Boron Trifluoride (BF3), Aluminium Chloride (AlCl3) some atoms have less than 8 electrons in their valence shell. Group…
What is sp3 Hybridization?
The process of formation of 4 equivalent orbitals from hybridization or mixing up of one S– and three P orbitals is known as sp3 hybridization.…
