scientists in a lab are working with two different samples of the element mercury. they know that the different samples are different isotopes. which property of the isotopes must be different? the atomic number the electric charge the element name the mass number

scientists in a lab are working with two different samples of the element mercury. they know that the different samples are different isotopes. which property of the isotopes must be different? the atomic number the electric charge the element name the mass number

Answer

Brief Explanations:

Isotopes of an element have the same atomic number (number of protons), same element name, and are neutral with the same electric - charge. The mass number (sum of protons and neutrons) is different for different isotopes.

Answer:

D. the mass number
