Homework: Ionic Bonding

Homework: Ionic Bonding

You are going to write notes summarising the basics of ionic bonding.

These notes must include:

• A labelled diagram showing the formation of ions.
• A labelled diagram showing the structure of an ionic compound.
• Definitions of the words on the following page.
• An explanation of the properties of ionic compounds (high melting/boiling points, not conducting electricity when solid, conducting electricity when dissolved/molten).

I have attached videos to help you, however I would encourage you to use other reliable sources to supplement e.g. the BTEC textbook.

There are slides where you can attach a picture of your notes, so that I can review them. 

There are some questions to answer at the end of the slides. You will need a periodic table to help you with some of the answers.

Definitions

• Ionic bond
• Ion
• Compound
• Proton (include mass and charge)
• Electron (include mass and charge)
• Valence shell
• Valence electron(s)
• Lattice
