Which of these elements has four total electrons in its outer p orbital

Amagnetic field "does not" interact with stationary electric charges. so, a.hope my answer you : )

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
