Radioactive Decay Concepts and Applications

The video tutorial explains radioactive decay processes using reference tables. It covers beta decay with phosphorus-32, beta positive decay with potassium-37, and alpha decay with francium-220. The tutorial emphasizes the law of conservation of mass and charge, and how to identify parent and daughter nuclides.

What is the purpose of the New York State reference table in the context of radioactive decay?

• To calculate the energy released during decay

• To find the atomic number of elements

• To list all known elements

• To determine the decay mode and half-life of isotopes

• Increases by 4

• Remains the same

• Decreases by 2

What is the atomic number of francium, which undergoes alpha decay?

• 88

• 87
