The scientist who is credited with discovering oxygen is Joseph Priestley, an English chemist and clergyman. He isolated oxygen in 1774 by heating mercuric oxide and noting the release of a gas that enhanced combustion.
I don't think there was a scientist because it was in ancient times sorry i couldn't help
The scientist who discovered the electron shell in 1913 was Niels Bohr. He proposed the Bohr model of the atom, which described electrons orbiting the nucleus in distinct energy levels or shells. This model helped explain the stability and spectral properties of atoms.
Ernest Rutherford is credited with discovering the nucleus of the atom through his gold foil experiment in 1909. He observed that most of the particles passed through the foil, suggesting that the atom is mostly empty space with a concentrated positive charge at the center, which he called the nucleus.
J.J. Thomson is credited with discovering the electron through his experiments with cathode rays in 1897. He observed that cathode rays were negatively charged particles and proposed that they were a fundamental component of all matter.

Joseph Priestly was the scientist who is credited with much of the progress in the biological sciences during the 18th century. He is usually credited with discovering oxygen.
Marie Curie is credited with discovering radium. She died of aplastic anemia, likely caused by her prolonged exposure to high levels of radiation during her research with radioactive materials.

one of the first antibiotics was actually discovered by a British scientist named Alexander Fleming. He is credited for discovering (penicillin)
Sir J.J. Thomson won the Nobel Prize in Physics in 1906 for discovering the electron. He conducted experiments on cathode rays that led to the identification of the particle.
