Orbitals

Question 1

What is an orbital?

Answer 1

It’s a 3D region around the nucleus that indicates the probable location of an electron

Question 2

What is are lobes?

Answer 2

They are the possible numbers of orbitals in each sub-energy shell, and electrons are found within them

Question 3

What are nodes?

Answer 3

The plane (Or planes) that the orbitals do not fill are called nodes, where the is a 0 probability density of finding electrons

Question 4

What are the characteristics of the s orbital?

Answer 4

It’s spherical, has 1 lobe, and 0 nodes (Electrons can be found in all possible spaces)

Question 5

What are the characteristics of the p orbital?

Answer 5

It’s dumbbell shaped, has 3 lobe, and 1 node (One region where the electron density is 0)

Question 6

What are the 3 p orbitals called?

Answer 6

Px, Py, and Pz

Question 7

What are the characteristics of the d orbital?

Answer 7

It has complex shapes, 5 lobes, and 2 nodes (Two regions where the electron density is 0)

Question 8

What are the characteristics of the f orbital?

Answer 8

It has VERY complex shapes, 7 lobes, and 3 nodes (Three regions where the electron density is 0)

Question 9

What happens to the orbitals as they move away from the nucleus?

Answer 9

They increase in size and the chance of finding electrons is decreased, the electron density is decreased
