Illustrate and describe the sequence in which ten electrons occupy the five orbitals related to an atoms d sublevel

In an atom, subshell is defined as the set of states in a given shell that have the same azimuthal quantum number (ℓ).  

For a d-subshell, the value of azimuthal quantum number (ℓ) is 3. Also, a d-subshell contains 5 atomic orbitals, namely , that can be occupied by 2 electrons each.

The filling of electrons in a subshell, such as the d-subshell, of a given shell is governed by the Hund's Rule of maximum multiplicity.

According to this rule, firstly all the 5 atomic orbitals of the d-subshell are singly filled and then the electrons are paired.

Since, a d-subshell can contain 10 electrons.

Therefore, firstly the 5 atomic orbitals are occupied with one electron each

Then the remaining five electrons, results in the pairing of electrons in each d-atomic orbital.

what is the volume occupied by 40 grams of argon gas (ar) at standard conditions? what volume, in liters, is occupied by 1.5 x 1023 

the answer is a. co2, this would be colder than the : )
