The central atom P is bonded to the five chlorine atoms by five single covalent bonds. So, the total number of single bonds is 5. The hybridization must be among one s orbital, three p orbitals and one d orbital each of which has a half filled orbital to share with the half filled orbital of each chlorine atom. So the hybridization can be written as sp3d. 1s, 3p and 1 d, a total of 5.
An easy way to find the hybridization is to count the number of bonds including the unshared electrons around the central atom. For double or triple bond count only one. If the total number of bonds including the number of unshared electron pairs is 6, then the hybridization will be sp3d2, a total of 6.
The central atom of PCl5 is P. In this case, phosphorous has an sp3d hybridization. It is connected to 5 other atoms, one more than the 4 for sp3 hybridization.
A pentavalent atom is one that can form 5 chemical bonds, for example nitrogen in HNO3, phosphorus in PCl5.
The name of the compound PCl5 is phosphorus pentachloride.
PCl5 -----> PCl3 + Cl2
In H2O, the central atom is Oxygen atom and it is sp3 hybridised

Phosphorus pentachloride (PCL5)
The name of the compound PCl5 is phosphorus pentachloride.
NCl5 does not exist bcoz nitrogen atom does not have d-orbitals to accomodate electrons from chlorine atoms and nitrogen cant accomodate more than 8 electrons in its valence shell. so its covalency exists only upto four.... pcl5 exists bcoz phosphorus atom has vacant d orbitals to accomodate electrons and thus pcl5 exists
PCl5 -----> PCl3 + Cl2
In H2O, the central atom is Oxygen atom and it is sp3 hybridised
Yes, PCl5 is a binary molecular compound.
a nucleus cant be a central atom. the nucleus is part of the atom. you are probably talking about why certain atoms are central atoms in a molecule and why some arent. the answer to that question is that the more electronegative atom will always appear as a central atom.
Carbon, the central atom, is sp2 hybridized.
