Unit 1 Atomic Structure and the Periodic Table (9CHO)

It might be challenging to ace Chemistry:( This is my condensed revision notes that cover the different areas as listed in the specification. Try to get as many marks in your Chemistry Unit 1 paper by understanding the basics and building up your knowledge. I achieved an A* in my Chemistry IAL and an A in my Chemistry As Level. I am sure you can do this too!

These revision notes for Edexcel A-Level Chemistry Unit 1 cover atomic structure and the periodic table in detail. Key topics include the properties and significance of subatomic particles, the principles of electron configuration, and the trends observed across the periodic table. Additionally, these notes explain periodic trends such as atomic radius, electronegativity, and ionization energy, and introduce mass spectrometry as a tool for determining relative atomic masses and isotopic composit...
