Which of the following statements are correct?

Due to its smaller size, F is the most electronegative element, while Cs is the most electropositive.
Because halogens lose some of their ability to attract electrons to themselves as they get larger, their electronegativity drops from F to I.
Although their electronegativities are in reverse order, Cl has a stronger electron affinity than F.
Due to the high energy required to add electrons to noble gases, their electron affinities are essentially nonexistent.
Therefore, each statement is true.
