Chpt 7 - Atomic Structure Electromagnetic Radiation Atomic Spectrum - Bohr Model Quantum Mechanical Model Orbital Shapes and Energies Electronic Structure.
Edexcel Unit 1 AS Chemistry
Electron arrangements
Electron clouds are 3D, not flat Electrons are spread out as much as possible, not usually round, and are moving rapidly These things are hard to see.
Section: 3.3 - Electron Configurations and Periodic Trends Electron Configuration – a shorthand notation that shows: – The number of electrons – The arrangement.
Chapter 5 Electrons in Atoms Anything in black letters = write it in your notes (‘knowts’)
