- Atoms, Elements and Electronic Structure
- Elements
- A substance that is made of only one sort of atom
- Atoms
- Smallest particles of an element
- Have a small central nucleus
- Made of protons and neutrons
- Surrounded by shells of electrons
- Protons +1
- Neutrons 0
- Electrons -1
- Number of electrons is equal to number of protons - no overall charge
- Electronic Structure
- Electrons occupy particular energy levels
- Shells closest to the nucleus are at the lowest energy levels
- If a shell is full the element is known as stable
