1. At) has the smallest electronegativity because it has the largest radius and the largest number of
protons.
2. At) has the smallest electronegativity because it has the smallest number of electrons.
3. F) has the largest electronegativity because it contains the smallest number of protons and it has
the smallest radius.
4. F) has the largest electronegativity because the electrons in element F have the largest attraction
to the nucleus.
