Electronegativity
An element's pull on
electrons in Chemical bond
4 Being highest EN
Linus Pauling
Fluorine
Between 0.4-1.7
Polar Covalent Bond
One atom has a stronger
pull on the electrons
Dipoles
Partial negative charge
>1.7
Ionic Bond
Complete transfer of electrons
between atoms.
Cation
Held together in fixed
ratios (Ex. 2H:1O)
Electrostatic attraction
Anion
Between 0-0.4
Non polar Covalent Bond
The atoms share electrons
Equally between them
Remain atoms,
(NOT ions)
Lewis Diagrams
The element and
outer/valence electrons
They are very simplified
These electrons are
involved in the bonds
Types of bonds between atoms
Lines to distinguish types of bonds
Show Ionic bonds
Displaying the transfer
of electrons as well as
showing charge
Show covalent bonds
Displaying lines that
represent a shared electron pair
The electrons are arranged in a
specific pattern around the symbol
