Chemical bond (Intramolecular force)

• 1. When 2 or more atoms share or transfer their valence electrons. 

• 1. A chemical bond between a cation and an anion where electrons are transferred. Typically a metal and nonmetal. 

• 1. A chemical bond between 2 or more nonmetals that are sharing electrons. 

• 1. A chemical bond between 2 or more metals where their electrons are delocalized and spread among the atoms. 

Ionic Bond (salt)

• A chemical bond between a cation and an anion where electrons are transferred. Typically a metal and nonmetal.

• 1. A chemical bond between 2 or more nonmetals that are sharing electrons. 

• 1. A chemical bond between 2 or more metals where their electrons are delocalized and spread among the atoms. 

Covalent Bond (molecule)

• 1. A chemical bond between a cation and an anion where electrons are transferred. Typically a metal and nonmetal. 

• 1. A chemical bond between 2 or more nonmetals that are sharing electrons. 

• 1.  A chemical bond between 2 or more metals where their electrons are delocalized and spread among the atoms. 

Metallic Bond (alloy)

Lattice Structure

• 1. When 2 or more atoms share or transfer their valence electrons. 

•  The 3-D structure of an ionic compound that minimizes repulsions between similarly charged ions in a repeated, every-other fashion. + - + - + - + - and so on. This is a very rigid structure with tight chemical bonds.

• Electrons that are not bound to a single atom or energy level, but flow between bonded nuclei to hold the atoms together

• 1. 2 or more chemically bonded atoms. 

Delocalized electrons

• The 3-D structure of an ionic compound that minimizes repulsions between similarly charged ions in a repeated, every-other fashion. + - + - + - + - and so on. This is a very rigid structure with tight chemical bonds.

• 1. Electrons that are not bound to a single atom or energy level, but flow between bonded nuclei to hold the atoms together. 

• 1.  2 or more chemically bonded atoms. 

• 1. A way of representing the ratio of atoms in a compound using the atomic symbols and subscripts.
