She was a scientist that helped discover nulcear fission. She pointed out that the total mass of the particles produced when the uranium nucleussplit was less than that of the original uranium nucleus.

She was a scientist that was one of the main people to discover nuclear fission. She was a very smart lady. She saw that the mass of the particles produced when the nucleus of uranium split, it was less than the nucleus before.

Well this so called Lise Meitner was a scientist that helped discover neclear fission. she probably found that the total mass of the particle help to produce when the uranium nucleus split. thats about all i got!

Lise Meitner was an Austrian-Swedish physicist that first identified nuclear fission. After she died, she got an element named after her. She deserved the nobel prize but didn't get what she deserved so they named that element after her. The element was called meitnerium.

She was a scientist. She helped discover nuclear fission. and pointed out that the total mass of the particles produces when uranium nucleus slpit was way less then the oringinal urnanium nuclues. So, she was pretty cool.

She was one of the scientists that helped discovered nulcear fission she figured out that it was split in half and did not have has much as it did before

Lise Meitner was the first to propose a theory to explain nuclear fission. Her theory was that it was so unstable that when a nuetron striked it, it would divide. which is what fission means to divide.

She was one of the scientists taht helped discover nuclear fission. She saw that the mass of the particles that were produced when the nucleus split. Then, the mass was less than before.

Lisa Meitner was the 1st to offer the theory to explain that the uranium-235 nucleus is so distorted. This told her that when the nucleus strikes it that it divides into 2 smaller nuclei. She was then the 1st person to discover Nuclear Fussion.Nuclear Fussion is the process of splitting a nucleus into many smaller nuclei.

Lise Meitner was a girl scientist that helped discover nuclear fission. She found that the total mass of the particles produced when the uranium nucleas splits was less then the original nucleus.

she was a scientist the help discover fission. she has pointed out the the tatal mass of the particles produced.

She was ascientist who helped discover the nuclear fission and she was reconised for doing it. She said that the total mass of the particles produced when uranium nucles split was less than of the orginal uranuim nucleus. Then there was an element named after her because she figured that out.

Lise Meitner was a Austrian physicist. She was the first to explain how nuclear fission works. She saw that the total mass of the partcles made when the element Uranium was split was less than the original. And then that missing mass, yeah, that was made into TONS of energy!

She was a scientist that helped find nuclear fission and pointed out that mass of the particles produced when uranium's nuclei split was lower then the original nucleus.

She was a female physicist. She found that the mass of the product was less than the mass that was started with in nuclear fission. This was because a small amount of energy was released in the process of fission.

Well Lise Metner was an Austrian physicist. She pointed out that thte total mass ofthe particles produced when the uraniujm nucleus split was less than that of the original urnaium nucleus. So technically she was the first to explain how nuclear fission occured.

She was a scientist that helped discover nuclear fission. She was an intellagent one that pointed out mass of the particles produced when uranium nucleussplit was less than that of the original.

She was an Audtrian scientist who helped discover the nuclear fission. She found the total mass of the particles produced when the uranium mucleus split in half and that made less of the nucleus.

She was a scientist that contributed to the discovery of nuclear fission. She pointed out that the total mass of the particles produced when the uranium nucleus split.
