Properties of Water and Electronegativity

The Importance of Water

Water is crucial to all living things.

Properties of Water

• Water is made of 3 atoms: 1 oxygen atom and 2 hydrogen atoms.

• The atoms are formed together through covalent bonding.

  • Water utilizes hydrogen bonding.

  • Electronegativity: The ability to attract electrons.

    • Fluorine, oxygen, and nitrogen atoms are electronegative because they are high in electrons.

Hydrogen Bonding

• A type of chemical bond between hydrogen and one of FON atoms (fluorine, oxygen, or nitrogen).

• To remember the 3 electronegative atoms use FON (Fluorine, Oxygen, Nitrogen).

• It causes the creation of positive and negative dipole within a molecule.

Dipole

• When an electronegative atom pulls electrons toward itself, that atom becomes more negative.

• Occurs due to an unequal sharing of electrons between atoms in a molecule.

• A charged molecule.
