Which of these singly ionized atoms of the same speed will curve most in a magnetic field?

Question

Quizplus · Accepted Answer

The amount of deflection of a charged particle in a magnetic field depends on the strength of the magnetic field, the speed of the particle, and the charge-to-mass ratio of the particle. Since all the atoms are singly ionized, they carry the same charge. The charge-to-mass ratio of helium (He) is the smallest among the given options, which means it will experience the largest deflection in the magnetic field. Therefore, He will curve the most.
