Chapter 8 - Periodic Properties of the Elements
8.1 Nerve Signal Transmission
- Nerve Transmission: Movement of ions across cell membrane is basis for transmission of
nerve signals, Na+ and K+ are pumped through membranes to opposite directions through
ion channels (Na+ OUT, K+ IN), ion size and other properties are periodic properties
(Properties whose values are predicted based on where the element is on the Periodic Table)
8.2 The Development of the Periodic Table
- Mendelev ordered elements by atomic mass, saw repeating patterns of properties
- Made Periodic Law - when elements are arranged, certain sets of properties recur
periodically
posing signs- Put elements with similar properties in same column, later arranged
elements according to Atomic Number (Moseley): better correlation with elemental
properties
8.3 Electron Configurations: How Electrons Occupy Orbitals
- Electron Configuration: Quantum Mechanical Theory describes behaviour of electrons
in atoms, electrons exist in orbital, description of the orbitals is called the Electron
Configuration - Ground state electron configuration of an atoms lists orbitals occupied by
its electron from lowest to highest energy = LOWER ENERGY ARRANGEMENT
Rules:
1) Lowest energy orbital fill first: 1s 2s2p3s3p4s3d (Aufbau (build-up)
principle)
2) Electron can only have 2 orientations, Up and Down, Only 2 electron can occupy the same
orbital and have opposing signs (Pauli Exclusion Principle)
3) If 2 or more empty degenerate orbitals are available, electrons occupy each singly with
spins parallel, until all orbitals have 1 electron (Hund's Rule)
8.4 Electron Configurations, Valence Electrons and the Periodic Table

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.

As a college student living on a college budget, I love how easy it is to earn gift cards just by submitting my notes.
