Overview

Chemical bonding explains why atoms combine and how they form stable substances. Atoms combine to reach lower potential energy and a more stable electronic arrangement, usually similar to noble gases. The chapter covers ionic bonding, covalent bonding, coordinate bonding, polarity, resonance, hydrog

Key Concepts

Atoms combine because a bonded system

Atoms combine because a bonded system has lower potential energy and greater stability. Most atoms try to achieve a noble gas-like configuration by ga

During bond formation

During bond formation, an atom gains, loses, or shares electrons until it has eight electrons in its valence shell. Hydrogen and lithium are exception

An ionic bond is the electrostatic

An ionic bond is the electrostatic force of attraction between ions formed by complete transfer of electrons from an electropositive atom to an electr

A covalent bond forms by mutual

A covalent bond forms by mutual sharing of electron pairs between atoms of similar or nearly similar electronegativities. Single, double, and triple b

A coordinate covalent bond is

A coordinate covalent bond is a covalent bond in which both electrons of the shared pair come from one atom. It is often represented by an arrow.

Learning Objectives

  • Explain why atoms combine to form chemical bonds
  • Describe ionic, covalent, coordinate, metallic, and hydrogen bonding
  • Apply the octet rule and identify its exceptions
  • Predict polarity using electronegativity and dipole moment
  • Use formal charge to compare Lewis structures
