  Elements on this side of the dark line
• Monoatomic


  An atom that forms 0 bonds
• Noble gases


  • Group exists as single atoms and are gases at room temperature
  • Have a full shell of outer electrons
  • Are unreactive (inert)
• Covalent bonds are usually made between atoms in substances which contain only non-metal elements
• Covalent bond


  A shared pair of electrons between two atoms that are attracted to each other
• Covalent molecules


  • Have a discrete number of atoms in their structure
  • Can be solid, liquid or gas
  • Need only a small amount of energy to break the weak intermolecular forces between the molecules
• Covalent molecules


  • Water (H₂O)
  • Silicon dioxide (SiO₂)
• Covalent network substances


  • Always solid
  • Have strong covalent bonds holding the atoms together
  • Require a great deal of energy to break
  • Have an undefined number of atoms in their structure
  • Their formula shows the ratio of atoms present
