6.

Choose the correct option according to the orbital diagram

a)

The orbital diagram matches to Nitrogen

b)

The orbital diagram matches to Carbon but is not correct

c)

The orbital diagram is missing two arrows

d)

The orbital diagram is not correct

7.

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

a)

Nitrogen is not correcly written.

b)

Silicon is not correctly written.

c)

Only Te and Mo are correctly written.

d)

None of the atoms is correctly represented.

e)

All the atoms are correctly represented.

8.

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

a)

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.

 

b)

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

 

c)

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.

d)

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

9.
a)

Both arrows in the 2p box should be pointing up

b)

There is nothing incorrect with this diagram

c)

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

d)

All the arrows should be pointing up.
