Isotopes
What is the purpose of a Geiger-Muller tube?
To detect radiation
What happens to the atomic number and mass number of an isotope that undergoes beta emission?
The atomic number increases by 1, and the mass number remains the same
What is the use of Cobalt-60 in medicine?

What is the primary difference between the atomic number and mass number of isotopes?
Isotopes have the same atomic number but different mass numbers.
What is the significance of the half-life of a radioactive isotope in understanding radioactive decay?
The half-life of a radioactive isotope is the time taken for half the atoms in a sample of the isotope to decay.
What is the effect of alpha decay on the atomic number and mass number of an isotope?
The atomic number decreases by 2 and the mass number decreases by 4.
What is the significance of Carbon-14 in archaeology?
Carbon-14 is used in archaeology to date organic materials.
Compare and contrast the effects of beta emission and alpha decay on the atomic number and mass number of an isotope.
Beta emission increases the atomic number by 1 and leaves the mass number unchanged, while alpha decay decreases the atomic number by 2 and the mass number by 4.
