Overview

Chemical bonding explains why atoms combine to form stable molecules and compounds. Atoms do not exist only as separate units in every case; many elements form molecules, and many compounds form because atoms gain, lose, or share electrons to reach stable electronic arrangements. The octet rule expl

Key Concepts

A chemical bond is the force

A chemical bond is the force of attraction between any two atoms or a group of atoms that results in a stable entity. Valence electrons are the outer-

Lewis dot structures show valence electrons

Lewis dot structures show valence electrons around the symbol of an element. For main-group elements, the group number helps predict the number of val

Atoms tend to undergo chemical changes

Atoms tend to undergo chemical changes that help them reach eight electrons in the outer shell. Helium is an exception because its only shell is compl

An ionic bond is the electrostatic

An ionic bond is the electrostatic attractive force that keeps cation and anion together to form a neutral compound. It forms when electrons are trans

A covalent bond is formed by

A covalent bond is formed by mutual sharing of a pair of valence-shell electrons so that both atoms attain octet or duplet. Shared pairs may form sing
