Elements and Pharmaceutical Importance

• Li+ and Mg2+ salts have similar solubility, for example, their carbonates, phosphates and fluorides salts have a low water solubility
• Reactivity of boron group

  • Ionize to form stable cation M3+
  • Al is highly reactive, forms oxide coating, B is chemically unreactive except at high temperatures
  • Al reacts with acids and alkalis
  • Al reduces metal oxides
  • Combine directly with halogens to form halides
