What are isotopes?
Think about the number of neutrons!
Name one isotope of hydrogen.
Consider the common types of hydrogen.
What defines an isotope?
Remember the difference between protons and neutrons.
True or False: All isotopes of an element have the same chemical properties.
Think about chemical properties linked to atomic structure.
A sample contains 100 atoms of an element with atomic number 6. If 80 are Carbon-12 and 20 are Carbon-14, calculate the average atomic mass of the sample.
Consider that the average mass is a weighted average based on proportions.
Describe how increasing the number of neutrons could affect the stability of an isotope and give an example.
Refer to the concept of nuclear stability and radioactive decay.
