Mini-Quiz: Isotopes

1. Is it possible for an element to have isotopes with different numbers of protons?

   Yes, that is the definition of an isotopeSorry, not correct. Try another button. It depends on the number of electrons the element hasGood try, but not right. Select another answer. No, because the element is defined by a specific number of protonsThat is correct. You know about isotopes.

   The less common isotopes are usually unstableCorrect. You know your stuff! The heavier the isotope, the more common it isOops! Wrong answer. Re-read the question and try again. All isotopes are commonSorry, not correct. Try another button.

3. What does the half-life of an isotope mean?

   It means that 1/2 of the atoms are isotopesGood try, but not right. Select another answer. It is the time it takes for 1/2 of the isotope atoms to decay into another materialThat is correct. You know about isotopes. It is 1/2 of the age of the isotopeSorry, not correct. Try another button.
