Print calculator Periodic Table Question 6 of 18 Map You cause a particle to move from point A. where the electric potential is 11.9 V, to point B, where the electric potential is -25.9 V. Calculate the change that occurs in the particle's electrostatic potential energy, when the particle is: an electron. Number a proton. Number a neutral hydrogen atom. Number a singly ionized helium atom (i.e., lacking one electron from its neutral state). Number O Previous 8 Give Up & View Solution Check Answer Next d Exit Hint

Explanation / Answer

for an electron:

electrostatic potential energy = V*q = (-25.9-11.9)*(-1.6*10^-19) = 6.048*10^-18 J

for proton:

electrostatic potential energy = V*q = (-25.9-11.9)*(1.6*10^-19) = -6.048*10^-18 J

for a neutral hydrogen atom:

electrostatic potential energy = V*q = 0 J

for a singly ionized helium atom:

electrostatic potential energy = -6.048*10^-18 J
