- Structures and Bonding
- Shells of an element
- Each shell represents a different energy level.
- Electrons are on the shells of an element. They are attracted by the positive pull of the nucleus.
- Eight electrons on their outer shells.
- Group 0, Noble gases.
- Stable and Unreactive
- Argon (Light bulbs), Neon (Lights), Helium (Balloons).
- Group 0, Noble gases.
- Atomic Structure
- The Periodic Table
- Horizontal rows= Periods.
- Vertical columns= Groups.
- In order of atomic numbers.
- Chemical bonding
- Covalent Bonding
- Sharing of Electrons
- Want eight electrons on their outer shells.
- Two none- metals
- BBC Bitesize
- Giant covalent structures
- Covalent lattices. Eg: Diamond.
- Sharing of Electrons
- Ionic Bonding
- Transferring Electrons.
- If an element gains an electron, it becomes negatively charged as it has one more electron than proton. If it loses an electron, then it becomes positively charged.
- Want eight electrons on their outer shells. Eg: 2,8,1 and 2,8,7. 2,8,1 loses an electron to become 2,8, and 2,8,7 gains one to become 2,8,8.
- None-metal and a metal
- BBC Bitesize
- Metals generally lose electrons, None-Metals gain them.
- Can create giant structures.
- Transferring Electrons.
- Metallic Bonding
- Two metals.
- Metals also have giant structures.
- Regular layers of positively charged ions. Delocalised electrons in between and around these ions.
- These delocalised electrons can carry an electrical charge.
- Metals can be galvanised to stop them from rusting. This is where they are dipped in zinc.
- Covalent Bonding
- Shells of an element
