http://www.ck12.org Chapter 8. Ionic and Metallic Bonding
ions that make up crystals arranged? What is responsible for the beautiful colors of minerals and gems? This chapter
will reveal the answers to these questions, as you learn about the composition and properties of ionic compounds and
of pure metals. In an ionic crystalline solid, positive and negative ions are arranged in an orderly, repeating fashion.
The colors are contributed by various amounts of transition metal ions in the crystals. The red color of rhodochrosite
comes from manganese(II) carbonate, MnCO 3. Metals also have a crystalline structure, which contribute to the
familiar properties of metals like malleability and electrical conductivity. We begin with a detailed look at how ions
form.
