The overall reaction in a chemical cell is shown below as the reaction takes place (look in image)

Your selected answer is correct. Zn, in the reaction, is being oxidized to its 2+ state. In this half reaction, the elemental zinc is dissolving back into the zinc solution-this can be seen by the state change from “s” to “aq”. Consequently, the copper electrode increases in mass as the Cu2+ is reduced back to elemental copper at the electrode.

Ifound this on google “these two compounds have a different ionic structure. caesium ion is larger in size when compared to the sodium ion. the charge gets more area to spread out evenly. so caesium chloride has a lower melting point than sodium chloride.” i hope this you for what your looking for
