H. Becquerel discovered that uranium was radioactive, i.e. was emitting energy which was unknown at the time.
Marie Curie and Pierre Curie did further work on radioactivity and discovered new elements, radium and polonium which were also radioactive.
Ernest Rutherford and his collaborator Soddy explored radioactivity systematically and discovered several new radioactive elements. More importantly they systematically developed procedures and concepts for defining radioactivity, such as radioactive half-life, activity versus time plots to better understand the energy emitted by radioactive elements: alpha particles (positive charge, mass of helium), beta particles (negatively charged particles or high energy electrons) and finally high energy electromagnetic radiation or gamma rays as they called it.

∙ 13y agoI assume you mean Marie Curie, Pierre Curie and Henri Becquerel. Basically, Becquerel discovered and theorized radioactivity, Marie Curie designed the experiment leading to the resultant discoveries, and Pierre Curie designed the critical apparatus used in the experiment (a piezoelectric electrometer).

What is the meaning of acronym SCIENTIST ARE GIFTED AND BORING in physics?
The given phrase is not recognised as an acronym. I would have thought that a 27-letter acronym should be pretty easy to identify.
Identify the source of the energy form?

How do you identify image on inclined mirrors?
Well, first you need to look at the mirrors. Then you identify the image.
What is the difference between radiation and radioactivity?
There is no difference in the meaning of the word. It is essentially the same thing. There are just two differenct forms of the word. You're still dealing with radium, Uranium, americium, and other radioactive elements either way.
Why a spectrum of an element is called fingerprint?
That's because it can be used to clearly identify an element; just as fingerprints can be used to identify a person.

Which technique enabled scientist in the S's to identify cell organelle?
Staining enabled scientist to identify cell organelles.
What scientist first discovered cells?
Robert Hooke was the first scientist to identify the cells in cork in 1665. He named them celluae that means small rooms. He printed about them in the book Micrographia. He studied them through his own made primitive telescope. V.Leewenhoek was the first scientist to identify the living cells. Robert Hook identified dead cells.
Which techniques enabled scientist in the 1800s to identify cell organelle?
Staining enabled scientist to identify cell organelles.
