We’ll kick off our new unit on STRUCTURES by looking at the structure of the the atom. YOU KNOW THIS STUFF ALREADY so the first part will be a recap, then we’ll go beyond the material you covered in Grade 8.
Here’s the presentation we will use in class: KS4 The atom
This is a useful resource to help you get up to speed with these ideas.
You’ve all been asking, pleading, begging for another assessment. Well, the good news is, you have one coming up next week – YEAH!
Block H students will take it on THURSDAY 1st OCTOBER.
Block D students will take it on FRIDAY 2nd OCTOBER.
Look through your notes from class, and go back through all the blog posts on atomic structure, the Periodic Table, electron configuration, metals vs non-metals, ionic and covalent bonding, Lewis structures, writing formulae, balancing equations et al.
COME AND SEE ME DURING TUTORIALS if you need help.
Lewis structures, also known as dot and cross diagrams, represent the arrangement of valence electrons in elements and compounds. This site has a detailed explanation of how to draw them.
These sites are ones we will use in class to practice. Feel free to practice at home too 🙂
YOU KNOW THIS STUFF ALREADY! You covered it in grade 8. This is just a recap. Click on the link to see the slides we will use in class. Atomic Structure Projections
Also, take a look at this link from the BBC Bitesize site. It will give you some good pre-reading on the topic and help you get up to speed.
