It has not been discovered yet
The (cell) nucleus is generally believed to have been discovered by Antonie van Leeuwenhoek. The nucleus of the atom was discovered by Ernest Rutherford.
Without it America would have never been discovered and we wouldn't exist
Some one else would have. Hitler was working on atom bomb during the war and was very close to making one. So, it was a matter of time when it would have been discovered.
Without the invention of the microscope, cells would either not ever been discovered or would have been discovered much later. This is because microscopes are the only way to see cells, and thus are the only way to prove their existence
An element is a substance in which every atom is the same. There are 118, 112 of which have been discovered.
Charles Darwin's greatest scientific contribution is his work on the Theory of Evolution. Without it, the fact that plants and animals evolved from its ancestors would not have been discovered.
An element with 120 protons would be unbinilium which hasn't been discovered yet. With 2 electrons would make it Ubn118+ which is an ion- not an atom so it is not on the periodic table.
Ernest Rutherford discovered protons in the nuclei of atoms in 1918, and James Chadwick discovered neutrons in 1932.
The atom contains 110 protons.
Probably, but how would we know?
If Marie Curie had not discovered radium, doctors would not have been able to cure cancer in the early stages. Marie Curie was one of the scientists that discovered radiation. She did not invent it. It is likely that given the experimentation going on at the time with radioactive materials, some other scientist would have discovered the same thing. It is likely that all the things that radiation now gives us (lasers, cancer therapy, atomic energy and weapons) would have been invented in a similar time line, although the pushing back of the perfection of the atom bomb would have had dramatic affect on the finale of WWII.
