Question

Electron density model of H_(2)O 1. How many hydrogen atoms are in a molecule of water? square 2. How many oxygen atoms are in a molecule of water? 3. What holds the hydrogen atoms to the oxygen atom? 4. The shading around the molecule represents the relative density of electrons shared by the atoms. What does this indicate about the density of electrons around the oxygen atom as compared to the density of electrons around the hydrogen atoms? 5. Where is the majority of negative charge on the water molecule?

Answer 1

1. There are 2 hydrogen atoms in a molecule of water.2. There is 1 oxygen atom in a molecule of water.3. The hydrogen atoms are held to the oxygen atom by covalent bonds.4. The shading around the molecule represents the relative density of electrons shared by the atoms. This indicates that the density of electrons around the oxygen atom is higher as compared to the density of electrons around the hydrogen atoms.5. The majority of negative charge on the water molecule is located on the oxygen atom.
