Describe the orbital diagram of an atom with six electrons. explain how this orbital diagram demonstrates hund's rule.

  Orbital diagram of an atom with six electrons is as shown here in the picture.

Here it satisfies the Hunds rule of maximum multiplicity.

As the electrons in the three 2p orbitals are singly filled instead of pairing up as singly filling each 2p orbital will give maximum multiplicity.

So each 2p orbital is singly filled first and after all the three 2p orbitals are singly filled then only pairing of electrons will take place,which is in accordance with Hunds rule of maximum multiplicity.

the product of the pressure and volume is also constant

i wish i could but this one is weird give me abc and i can solve it.
