Topics in Chemical Bonding

1

Lewis Symbols and Electronic Configuration

  • Lewis symbols represent valence electrons as dots around the element symbol
  • Noble gases (Group VIIIA) have 8 electrons in their valence shell (except He with 2)
  • Elements try to achieve noble gas configuration through bonding
2

Octet Rule and Electronic Theory of Valence

  • Atoms tend to achieve 8 electrons in their valence shell (octet rule)
  • Helium follows duplet rule (2 electrons in valence shell)
  • Elements achieve stability by gaining, losing, or sharing electrons
3

Ionic Bonding

  • Formed between metals and non-metals through electron transfer
  • Metal atoms lose electrons to form cations (positive ions)
  • Non-metal atoms gain electrons to form anions (negative ions)
4

Covalent Bonding

  • Formed between non-metals through electron sharing
  • Shared electrons belong to both atoms in the bond
  • Single bond: one pair of electrons shared (H-H)
