BI110 Chapter Notes - Chapter 1-5: Hydrogen Bond, Covalent Bond, Chemical Polarity
Document Summary
Describe the basic properties of water molecules. Explain how the polarity of water molecules results in hydrogen. Summarize the unique properties of water that are important for. Our bodies contain more water than any other compound. Physical and chemical properties: only natural substance that exists in each of the three. As a result, water stores a tremendous amount of thermal energy: considered the universal solvent because it is capable of dissolving so many substances. Water molecules easily adhere to other water molecules and many other polar substances: molecular structure. Two hydrogen molecules and one oxygen molecules. To fill its valence shell, oxygen shares a pair of electrons with each of the two hydrogen atoms. This unequal sharing gives oxygen a partial negative charge, and hydrogen a partial positive charge. Due to the geometry of the electron orbitals surrounding oxygen, water molecules have a bent shape. Water molecules have a total of four pairs of valence electrons.
