Question 2

What is the charge of the nuclues?

Answer 2

• Positive.

- Consists of Neutrons and Protons.

Question 3

What are the energy levels of the shells further from the nucleus?

Answer 3

• Energy shells further away from the nucleus are at a higher energy than energy shells close to the nueclues.

Question 4

What happens if the atom absorbs electromagnetic radiation?

Answer 4

• Electron can move from an lower energy shell to a higher energy shell.
  +
  Atom can emit electromagentic radiation and the electrons return to the lower energy shell.
