the 4th shell

Question 18

What are sub-shells?

Answer 18

orbitals of the same type in an energy level

Question 19

Arrange these terms in size order smallest to biggest : Sub-shells, Shells, Electrons, Orbitals

Answer 19

Electrons, Orbitals, Sub-shells Shells

Question 20

How are orbitals filled in terms of energy?

Answer 20

filled from the lowest energy (first shell) first, in order of increasing energy

Question 21

Which sub shell has a higher energy - 3d or 4s?

Answer 21

3d, which means 4s fills before 3d

Question 22

State the order of sub shell filling up to 4d.

Answer 22

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 4d

Question 23

What property do electrons have that allows them to occupy the same orbital?

Answer 23

a property called spin

Question 24

Electrons have a property called spin. Why does this allow electrons to occupy the same orbital?

Answer 24

When anything with a charge spins, a magnetic field is produced. one electron will spin one way while the other electron spins the other way. this gives opposing magnetic fields which we represent with an arrow. this is the only way electrons can share an orbital, as there is now some attraction between them

basically, electron spins, create magnetic field, opposing magnetic fields, attracts each other
