Which of the following periodic properties increases as you move from left to right across the periodic table? A.
nuclear charge
B.
All of these answer choices are correct.
C.
electron affinity
D.
electronegativity

the answer choice is B

Explanation:

as we move from left to right , the atomic size decreases due to higher number of protons in the nucleus, which are able to attract the electrons more strongly. and so the electronegativity and  electron affinity increases for the same reason. the nuclear charge increase due to more protons , and without an increase in inner electrons , there is less shielding effect. so effective nuclear charge increases.
