Choose the correct option according to the orbital diagram

• The orbital diagram matches to Nitrogen

• The orbital diagram matches to Carbon but is not correct

• The orbital diagram is missing two arrows

• The orbital diagram is not correct

According to the image which one of the following statement is correct?

• Nitrogen is not correcly written.

• Silicon is not correctly written.

• Only Te and Mo are correctly written.

• None of the atoms is correctly represented.

• All the atoms are correctly represented.

To represent 3p3 can we use the following diagram? (click on the image)

• Yes, because very orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

   

• Yes because the spin of the 2nd electron depends on the spin of the 1st electron, even though they are in the same orbital.

   

• No, because very orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

• Yes because the spin of the 2nd electron depends on the spin of the 1st electron, even though they are in the same orbital.

• Both arrows in the 2p box should be pointing up

• There is nothing incorrect with this diagram

• In the 2p box there should only be 1 electron in the first 2p box and one in the 2nd 2p box

• All the arrows should be pointing up.

Which orbital shows a violation of Hund's Rule?

• A

• B

• C

• D
