a chemical bond is a lasting attraction between atoms, compounds that enables the formation of larger chemical molecules/compounds

Types of Chemical Bondings
|
Chemical Bond |
Description |
|---|---|
|
covalent bond |
bond in which one or more pairs of electrons are shared by two atoms |
|
polar covalent bond |
covalent bonds in which the sharing of the electron pair is unequal (electrons spending more time around the more nonmetallic atom, are called polar covalent bonds) |
|
ionic bond |
bond in which one or more electrons from one atom are removed and attached to another atom, resulting in positive and negative ions which attract each other |
|
metallic bond |
properties of metals suggest that their atoms possess strong bonds, yet the ease of conduction of heat and electricity suggest that electrons can move freely in all directions in a metal |
|
hydrogen bond |
differs from other uses of the word “bond” since it is a force of attraction between a hydrogen atom in one molecule and a small atom of high electronegativity in another molecule. That is, it is an intermolecular force, not an intramolecular force as in the common use of the word bond |

van der Waals bond |
attractive forces between molecules in a liquid |
