Radium and polonium are natural radioactive chemical elements, discovered by Pierre and Marie Curie in 1898.
French scientist Henri Becquerel discovered radioactive elements.
All chemical elements after uranium and promethium, technetium.
nothing They're overall work; they discovered Atomic Fission.
She discovered the elements radium and polonium.
40 elements are discovered uptil now
Yes, radium and polonium are radioactive elements.
The Curies discovered two radioactive elements: polonium and radium.
Marie currie
No. The Curies did not discover uranium. They discovered polonium and radium, of which polonium is more radioactive.
She discovered the elements Polonium, which was named after her homeland, and radium. Polonium is 4x more radioactive than uranium and radium is 10x more radioactive than uranium.
ernest Rutherford _______________________________________________________________ Radioactive decay was actually discovered in 1896 by Henri Bacquerel. Ernest Rutherford discovered the formula of radioactive decay (Such as the falk-life, differences between alpha and beta decay and even how the elements become new elements after the decay), but he did not discover the radioactive decay himself.
Mono isotopic elements are stable isotope of an element.From 80 isotopic elements there are 26 radioactive elements discovered up till now.These mono isotopic may or may not be radioactive if they are radioactive they have halve lives.
