Question

radium nucleus
radon nucleus
which process does the image illustrate?
(1 point)
○ chemical change
○ nucleation
○ transmutation
○ composition

Explanation:

• Chemical change: Involves changes in the arrangement of electrons around atoms, not the nucleus.
• Nucleation: Refers to the process of forming a nucleus (like in crystal formation), not relevant here.
• Transmutation: Is the conversion of one element (radium) into another (radon) through a nuclear process (alpha decay as indicated by the alpha particle emission in the image).
• Composition: Deals with the makeup of a substance in general terms, not a nuclear - level transformation.

Answer:

transmutation
