Small molecules

• Covalent bond

  • A bond between atoms formed when atoms share electrons to achieve a full outer shell of electrons
• Molecule

  • Collection of two or more atoms held together by chemical bonds
• Small molecules usually consist of:

  • Gases or liquids
• Properties of substances with small molecules

  • Strong covalent bonds holds the atoms together
  • Has a low melting and boiling point to overcome the weak intermolecular forces
• They do not conduct electricity because the molecules do not have an overall charge
