# Atomicity of white or yellow phosphorus is 4 and it is represented as P4 molecule, calculate the value of expression x.yz regarding this molecule.

Where, x: Total number of vertex angles in P4 molecule

y: Total number of lone pairs in P4 molecule

z: Total number of P---P bonds in P4 molecule.

#### Atomicity of white or yellow phosphorus is 4 and it is represented as P4 molecule.

Where x: Total number of vertex angles in P4 molecule =12.

y : Total number of lone pairs in P4 molecule =4.

z : Total number of P---P bonds in P4 molecule =6.

Now,

x.yz=12×46=8

Thus, the value of expression x.yz regarding this molecule is 8.
