Chemical Bonding

• Bond Types:

  • Covalent
  • Ionic
  • Metallic
• Covalent Bonding: 2 nonmetal atoms share electrons to form a bond.
• Ionic Bonding: bond formed by the transfer of electrons. (Mostly Metal & Nonmetal)
• Metallic Bonding: the attraction of valence electrons for the positive nucleus of metallic atoms, gives metals their properties, based on the sea of mobile electrons
• Covalent Bonding Properties:

  • low melting points
  • likely to be gas or liquid
  • doesn't easily dissolve in water
  • cannot conduct electricity
• Molecular Compound: a substance with covalent bonds. (Similar properties to covalent bonds)
• Ionic Compounds:

  • forms a lattice crystal structure that's strong.
  • can dissolve in water
  • high melting point
  • conducts electricity when molten
