Unit 2 · Compound Structure and Properties

Chapter 2.2

Ionic Solids, Metals, and Alloys: How Solids Are Built

Why does a copper wire bend where a salt crystal cracks, and why does adding a little carbon turn soft iron into steel? Draw the particles and the answers are already in the picture.

lesson 6 of 45

By the end

  1. 01Model an ionic solid as a repeating array that maximizes attractions and minimizes repulsions
  2. 02Model a metal as cations in a sea of delocalized electrons
  3. 03Distinguish interstitial from substitutional alloys and predict how each changes the metal
