2
Q
What is the charge of the nuclues?
A
- Positive.
- Consists of Neutrons and Protons.
3
Q
What are the energy levels of the shells further from the nucleus?
A
- Energy shells further away from the nucleus are at a higher energy than energy shells close to the nueclues.
4
Q
What happens if the atom absorbs electromagnetic radiation?
A
- 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.
