Larger nuclear charge lowers energy, more electrons in an orbital lowers energy.

Larger nuclear charge lowers energy, more electrons in an orbital increases energy.

Smaller nuclear charge lowers energy, more electrons in an orbital lowers energy.

Smaller nuclear charge lowers energy, more electrons in an orbital increases energy.

None of the above statements is generally correct.
