Study Notes
Water Molecule Structure
- Composed of one oxygen atom and two hydrogen atoms, creating a bent molecular shape.
- Oxygen carries a slight negative charge due to the unequal sharing of electrons.
Oxygen Atom
- Exhibits a partial negative charge in a water molecule.
- Attracts electrons more strongly than hydrogen, leading to polar characteristics.
Hydrogen Atoms
- Each hydrogen atom carries a slight positive charge.
- This positive charge arises from the unequal sharing of electrons with the oxygen atom.
Covalent Bonds
- Water molecules are formed through covalent bonds, where oxygen and hydrogen share electrons.
- This sharing is key to the stability and properties of the water molecule.
Hydrogen Bonds
- Hydrogen bonds occur between different water molecules, contributing to water's unique physical properties.
- A hydrogen bond specifically involves the hydrogen atom of one water molecule and the oxygen atom of another.
Importance of Hydrogen Bonds
- These bonds are essential for the cohesion and surface tension of water.
- They influence various water properties, including its high boiling point and solvent capabilities.
