5.1 - Electron structure

Question 1

What is electron configuration?

Answer 1

The arrangement of electrons in an atom

Question 2

What is the principle energy levels(n) used for ?

Answer 2

Used to number the energy levels
- The lower the number, the closer the shell is to the nucleus
- The higher the number, the greater energy of the electron and the further away the shell is to the nucleus

Question 3

How many electrons can the first four energy levels hold?

Answer 3

1 =
2 = 8
3 = 18
4 = 32

Question 4

What is the link between the distance of an electron and the nucleus to the energy of the electron?

Answer 4

The further away an electron, the weaker the attraction and the higher its energy level
