Gallium has 31 electrons (₃₁Ga 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰ 4s² 4p¹) and if loses 13 electrons, gallium would have configuration of noble gas argon with 18 electrons (₁₈Ar 1s² 2s² 2p⁶ 3s² 3p⁶), but that is not possible, so gallium only loses three electrons and has electron configuration:
₃₁Ga³⁺ 1s² 2s² 2p⁶ 3s² 3p⁶ 3d¹⁰.

D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.

<u>Explanation: </u>

Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.

When the temperature increases, the molecules move farther apart as much as possible.

When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.
