Question

According to the work of the Curies, which action would increase the radioactivity of polonium?

a. Dissolve the polonium in a solvent.
b. Heat the polonium until it becomes a gas.
c. Expose the polonium sample to light.
d. Increase the amount of polonium.

Answer 1

Of Course D) Increase the amount of Polonium.
You want "Increase" the Radioactivity, And since Polonium is himself radioactive, you need to increase its amount.

Hope this Helps :)

Answer 2

Answer;

Increase the amount of Polonium

Explanation;

• Pierre and Marie Curies are known for their work in the study of radioactivity that led to the discoveries of new radioactive elements radium and polonium. Polonium was named after Marie's home country, Poland.
• Polonium is a rare natural element, it may be found in uranium ores which is uneconomical to extract. Therefore, it is obtained from the bombarding of bismuth-209 with neutron to get bismuth-210, which then undergoes radioactive decay to form Polonium.
• According to Curies increasing the amount of polonium would increase the radioactivity of Polonium element. Polonium undergoes alpha decay to emit alpha particle and is therefore used as a source of alpha particles.
