Bonds

Chemical bonds:

a type of interaction between atoms that results from atoms sharing or transferring valence elctrons; causes atoms to stay close in proximity

Covalent Bond:

two atoms share a pair of valence electrons

Ionic Bond:

difference in electronegativity >1.5

Double Covalent Bonds:

two atoms share multiple valence electrons

Polar Bonds:

difference in electronegativity between 0.5 and 1.5

Non-polar Bonds:

difference in electronegativity <0.5

Strong Chemical Bonds

Weak Chemical Bonds

Hydrogen Bonds:

attraction between a partially positive charged atom within a polar molecule and a partially negatively charged atom within a polar molecule

Van Der Waals Interactions:

molecules or atoms in close proximity can be attracted by fleeting charge differences
