they all have different mass numbers. And the reason for having different mass numbers should be due to having different neutron numbers: 1H having zero neutron; 2H one neutron; ³H two neutrons. QUESTION Element mercury has six isotopes: 198Hg, 199Hg, 200Hg, 201Hg, 202Hg, and 204H.. The abundance (frequency) of each of these isotopes is measured to be 10.20%, 16.90%, 23.40%, 13.10%, 29.90%, and 6.500%, respectively. Calculate the average atomic mass for mercury. This result should be very close to the number you can find in the Hg box in the periodic table. Hint: You can solve this question if you carefully exam the solution procedures you already exercised in the previous Questions #1 through #3. For your answer, type in only the number down to the second digits after the decimal point. Do not type in the unit that is year old.

Question
ISOTOPES Isotopes are atoms that have the same atomic number but different mass number. Most elements have two or more isotopes. For example, there are three isotopes of hydrogen: 1H, 2H, ³H. Since these isotopes are all hydrogen element, they should obviously all have the same atomic number of 1, but as you can see they all have different mass numbers. And the reason for having different mass numbers should be due to having different neutron numbers: 'H having zero neutron; 2H one neutron; ³H two neutrons. QUESTION Element mercury has six isotopes: 198Hg, 199H9, 200Hg, 201H9, 202H9, and 204H9. The abundance (frequency) of each of these isotopes is measured to be 10.20%, 16.90%, 23.40%, 13.10%, 29.90%, and 6.500%, respectively. Calculate the average atomic mass for mercury.
