Would you use uranium 235 or thorium 232 to date a sample that was about million years old?
Uranium dating is recommended. Thorium dating (but with the isotope 230Th, not with the isotope 232Th) is recommended to minerals old of up to 500 000 years.
How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.
Which isotope would be best for measuring the age of a rock layer estimated to be about one million years old?
Geologists use radioisatope pairs to determine the age of rocks about 1 million years old. one pair is 238u which spontaneously decays to 206pb.
What has the mass number of 41?
The substance would be an Isotope of the element Potassium.
How do you carbon date rocks 10 million years old?
You cannot. Carbon dating is not useful for dating things more than about 50,000 years old. You would have to use a different radioisotope to date something 10 million years old. Potassium-Argon dating would work for some rocks.

The frequency would be 1 million Hertz.
