O At has the smallest electronegativity because it has the largest radius and the largest number of
protons.
At has the smallest electronegativity because it has the smallest number of electrons.
O Fhas the largest electronegativity because it contains the smallest number of protons and it has
the smallest radius.
OF has the largest electronegativity because the electrons in element F have the largest attraction
to the nucleus.
