Final answer:
The total charge of the polonium nucleus is +1.346 x 10^-17 coulombs, calculated by multiplying the number of protons (84) by the charge of one proton (+1.602 x 10^-19 coulombs).
Step-by-step explanation:
The total charge of the polonium nucleus is determined by the number of protons it contains, as protons carry a positive charge. A neutral polonium atom has 84 electrons, and since it is neutral, it must have the same number of protons to balance out the charges. Therefore, the polonium nucleus has 84 protons. Since each proton has a charge of +1 elementary charge, or approximately +1.602 x 10-19 coulombs, the total charge of the polonium nucleus can be calculated as:
Total Charge = Number of Protons x Charge of One Proton
Total Charge = 84 x (+1.602 x 10-19 C)
Total Charge ≈ +1.346 x 10-17 coulombs
