The P2 molecule of phosphorus is not found because of the larger size of the phosphorus atom. The phosphorus is so larger that the p-orbitals which are required to overlapp sideways , are unable to overlapp sufficiently to make a pie bond. Below is the structure of oxygen atom that is showing π-bond But phosphorus

What are the characteristics of a lone pair? Characteristics of a lone pair Lone pair are the pair of electrons that do not take part in any chemical bond. They affect the symmetry of molecule or the shape of molecule as they interfere with the other electrons of the molecule . The electrons of lone
In case of PF3 the size of F is small and thus it approaches near to the central atom that is P. as it approaches near to P there comes the repulsion between the bond pairs, which widens the bond angle and makes it larger than in case of PCl3. Here two types of forces
At surface of a liquid will their will be no forces (forces by molecules) acting on molecules in opposite directions such that the net force between molecules (only at surface) will be zero? If exists how surface area of a liquid contracts? In the light of above concept let me explain a simple thing that
See the ion is a proper charged particle, but dipole is a neutral olecule which is having polarity in it . the dipole is having temporary charge where as the ion is having a permanent charge. Now lets see the cases Case 1 :- Ion – dipole attraction Here a permanent ion is attracting a
Here you can see the hybridization of both is same , both of these two elements have seven electrons in outermost shell and below is the diagram showing the electrons filled in s-subshell and p-subshell . one orbital of s- subshell and three orbitals of p-subshell are used during hybridisation. So the type of hybridization
In case of methanoic acid the carbon atom joined to the carboxyl group is attached to only hydrogen atoms which are not able to increase the electron density. HCOOH But in case of ethanoic acid we have a methyl group attached to the carbon of carboxyl group , which is electron releasing group and it
Chemical bond may be defined as the force of attraction by which two atoms are held together. The chemical bonds lead to the formation of molecules and crystals. There are various kind of bonding that we see around us. Covalent bond A covalent bond is formed by mutual sharing of electrons between two atoms. For
The word mole means pile up . This concept originated from a simple problem that was faced by the scientists to calculate the reactions. they needed a concept that could relate number of molecules with the weight. A mole of a substance is equal to as many molecules of that substance as there are number
Step 1: write the configuration of element and then show the valence elactrons around the symbol of element . Step2: make the bonds around the atom according to its valency and use the electrons for making the bonds. Step3: Now see if there are any unshared electrons pairs. These are your lone pairs. See the
