B. They came up with the term “radioactivity.”
C. They conducted experiments with uranium-containing minerals and pure uranium.
E. They discovered two new radioactive elements
Answer:
They came up with the term “radioactivity.”
They conducted experiments with uranium-containing minerals and pure uranium.
They discovered two new radioactive elements.
Explanation:
As we know that the radioactivity is discovered by Marie and Curie and as per the experimental verification of the theory given by them we can say that rate of decay of a radioactive sample is directly proportional to the number of the radioactive same present at that time.
So it is given as
[tex]\frac{dN}{dt} = -\lambda N[/tex]
so here they also discovered two new radioactive substance apart from all the experiments related to the Uranium
