Types of Radioactive Decay

Examine the nuclear reaction: mc007-1.jpg. Why is this classified as a nuclear reaction rather than a chemical reaction?

A change has occurred in a nucleus.

What is a key difference between chemical and nuclear reactions?

Chemical reactions involve electron rearrangements. Nuclear reactions involve changes to the nucleus.

A large atom decays and emits a particle. After the reaction is complete, the atom's mass has changed substantially. What kind of particle has most likely been emitted?

alpha particle

What is the most penetrating kind of radiation product that can be shielded with aluminum foil?

beta particles

Which can have either a positive charge or a negative charge when they are released during radioactive decay?

beta particles

An atom bonds with another atom. What is the best classification for this reaction?

chemical

What can form as a result of a chemical reaction?

compounds
