Sulfur has a lower ionization energy than chlorine because 

the effective nuclear charge of sulfur is less than that of chlorine. 
the effective nuclear charge of sulfur is greater than that of chlorine. 
False; sulfur has a greater ionization en- ergy than chlorine. 
sulfur elevates one of its p electrons to a d orbital, thus making it easier to remove the electron.

F is bigger than F because 

F has one more electron which causes greater electron repulsions in the outer orbitals, thus expanding the electron cloud. 
Fhas one more electron so there is less effective shielding of the nuclear charge. 
F has one less electron so there is less effective shielding of the nuclear charge. 
F has one more electron which causes less electron repulsions in the outer orbitals, thus expanding the electron cloud.

What is the primary reason that atomic radius decreases as you move from left to right across the periodic table even though the number of electrons is increasing?

All atoms in a given period of the table are the same size because the same main energy level is being filled.
As electrons are added, they go into orbitals in new primary energy levels which are further from the nucleus so the atoms get larger.
Increasing effective nuclear charge more strongly attracts the outermost electrons so the atoms get smaller.
There is no clear trend, the atoms all have different radii.
