3.1.3.6 Bond Polarity

define electronegativity

the ability of an atom to attract electrons in a covalent bond towards itself

which element has the highest electronegativity

Fluorine

which element is the least electronegative

Caesium

Name 3 factors which affect electronegativity

nuclear charge, atomic radius, shielding

define sheilding

the shells between the nucleus and outer electron

define non-polar

no difference between two elements in electronegativity

define polar

difference between two elements in electronegativity

what does delta positivity represent

the less electronegative element

what does delta negative represent

the more electronegative element

what can a difference in electronegativities induce

permanent dipole
