Study Notes
### Water Molecule Structure
- A water molecule is composed of two hydrogen atoms and one oxygen atom.
- Electrons are shared equally between the hydrogen and oxygen atoms in a water molecule.
### Bond Type in Water Molecules
- The bond type between hydrogen and oxygen in a water molecule is an ionic bond.
### Polarity in Water
- Water molecules are polar due to the unequal sharing of electrons between the hydrogen and oxygen atoms.
- Oxygen has a higher electronegativity than hydrogen, making it attract the shared electrons more strongly. This gives the oxygen side of the water molecule a partial negative charge and the hydrogen side a partial positive charge.
Water Molecule Structure
- A water molecule consists of two hydrogen atoms and one oxygen atom.
- The bond between hydrogen and oxygen in a water molecule is a covalent bond, not an ionic bond.
Water Molecule Polarity
- Electrons in a water molecule are not shared equally between hydrogen and oxygen atoms.
- Oxygen in a water molecule has a higher electronegativity than hydrogen, causing an uneven distribution of electrons.
- The unequal sharing of electrons contributes to the polarity of the water molecule, creating partial positive charges on the hydrogen atoms and a partial negative charge on the oxygen atom.
Hydrogen Bonding
- The attraction between the opposite charges in a water molecule creates a strong hydrogen bond.
- Hydrogen atoms in a water molecule are not attracted to each other because they have similar charges.
- The charge differences between hydrogen and oxygen atoms are the primary reason for the bond formation in water.
