2.1.4 Covalent Bonding

• What is Covalent Bond?

  Covalent Bond is a shared pair of electrons between two atoms.
• Describe the structure and properties of simple molecular covalent substances.

  Do not conduct electricity (no ions), Small molecules, Weak intermolecular forces, Low melting and Boiling Points.
• How do intermolecular forces change as the mass/size of the molecule increases?

  They increase. That causes melting/boiling points to increase as well (more energy needed to overcome these forces).
