2. Marie Curie is famous for
discovering the element
Radium.
Its atomic number is 88 and
its symbol is Ra. She
discovered it in 1898.

3. Marie was interested in the study of radiation, which was discovered by
Becquerel in 1896. So she decided to experiment with pitchblende which is a
major ore of Uranium and Radium. She discovered that the pitchblende also
contained Radium.

4. People back in 1898 were very sexist and Marie was a
female scientist so other male scientist found it very hard to
believe that she was capable of doing any original work that
she was involved in. Only her husband believed in her and
worked with her.

5. Marie Curie discovered radium which now is used for x-rays.
Without radium, then you wouldn't know if your bones are
broken or not which is quite serious.
X-Rays

6. Those Authority would not believe that Marie discovered
Radium because she was a woman and people were very
sexist back then and they probably thought that someone
else discovered it and she took the credit.
Or they would praise her for her great discovery and say it
is a scientific revolution.
