Homework: Atomic Structure

Atomic Structure

You are going to write notes (no more than a page) summarising the basics of atomic structure.

These notes must include:

• A labelled diagram of an atom.
• Definitions of the words on the following page.
• A brief summary of the key information.

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. 

The topics discussed will be tested at the start of next week's lesson. There are some multiple choice questions to answer at the end of the slides. You will need a periodic table to help you with some of the answers.

Definitions

 

• Atom
• Element
• Proton (include mass and charge)
• Neutron (include mass and charge)
• Electron (include mass and charge)
• Nucleus
• Shell
• Mass number (relative atomic mass)
• Atomic number (proton number)
• Isotopes
