Explain the meaning of the term electronegativity
It is the attraction by an atom for a bond pair of electrons.
1 of 7
The electronegativity of an element is best described as
its attraction for a bond pair of electrons
2 of 7
most bonds
have a mixture of ionic and covalent properties
3 of 7
electronegativity is measured using
the pauling scale
4 of 7
covalent bonds become polarised when
there are differences in electronegativity
5 of 7
an example of a non-polar molecule with polar bonds is
CO2
6 of 7
there's stronger attraction between two atoms if
bond enthalpy is high and bond length is short
