a scientist is trying to determine whether a certain substance is radioactive. which question would be most helpful to ask?\ndoes the substance have a positive electric charge or a negative electric charge?\ncan the substance be used to generate electricity in a power plant?\ndo the atoms that make up the substance have nuclei that split apart over time?\ndo the nuclei of the substances atoms contain more neutrons than protons?

Answer

Brief Explanations:

Radioactive substances have unstable nuclei that decay over time, often involving nuclear - splitting. Charge is not related to radioactivity directly. Ability to generate electricity doesn't define radioactivity. Having more neutrons than protons is not the most definitive sign compared to nuclei splitting.

Answer:

Do the atoms that make up the substance have nuclei that split apart over time?
