Electronegativity

HideShow resource information
Define electronegativity
The ability to attract bonding electrons in a covalent bond
1 of 7
What scale is electronegativity measured on?
Paulings Scale
2 of 7
What is the most electronegative element?
Fluorine
3 of 7
Does electronegativity increase or decrease across the periods?
Increase
4 of 7
Why are diatomic molecules non polar?
As they have equal electronegativities meaning the electrons are equally attracted to both nuclei and so no dipole is created.
5 of 7
What causes a dipole to form between two atoms?
A great difference in electronegativities
6 of 7
What is a dipole?
A difference in charge between two atoms due to a shift in electron density
