Why do elements with more protons generally have a higher effective nuclear charge?

Because they have more inner electrons causing more shielding.

Because they have fewer inner electrons causing less shielding.

Because the increased protons directly increase the nuclear charge.

Because the increased protons decrease the nuclear charge.
