(Hint: what elements were synthesized in the first 3 minutes since the Big Bang?)

2. How can we estimate the age of the solar system?
2.1 What is radioactive decay?
2.2 What are the underlying assumptioms of the tecnique?
2.3 What type of daughter product would be a convenient choice (gas, solid)?
2.4 What objects in the solar system could be used for this?
