Leo Szilard invented the atomic bomb in 1933 while studying possible ways to more effectively perform atomic transmutation experiments with neutrons, that he was working on at the tim in London.
What else can I help you with?
The invention of the atomic bomb was partially based on whose studies?
The invention of the atomic bomb was partially based on the studies of Albert Einstein and his theory of relativity that led to the understanding of mass-energy equivalence, as well as the work of physicist Enrico Fermi on nuclear reactions and Otto Hahn and Fritz Strassmann's discovery of nuclear fission. These contributions played a role in the development of the scientific principles behind the atomic bomb.
State the periodic law on which Mendeleev's Periodic table was based and why and how this periodic law changed?
Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses. This law changed with the discovery of atomic number by Moseley which stated that the properties of elements are a periodic function of their atomic numbers, leading to a more accurate and modern periodic table based on atomic number.
How did Ernest Rutherford change the atomic model based on his experimental results?
Ernest Rutherford's famous gold foil experiment led to the discovery of the atomic nucleus. This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.
Why was Moseley able to resolve the discrepancies in Mendeleev's table when Mendeleev could not?
Moseley's discovery of atomic number allowed for organizing elements based on their atomic number rather than atomic weight, leading to a more accurate arrangement of elements. Mendeleev's periodic table was based on atomic weight, which resulted in discrepancies. Moseley's insight helped to resolve these discrepancies and create a more precise periodic table.
How did Henry Moseley affect the development of the periodic table?
He discovered that each element has its own atomic number.In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.

Whose studies were partially based on the discovery of the atomic bomb?
The studies of physicist J. Robert Oppenheimer were significantly influenced by the discovery and development of the atomic bomb, particularly through his role as the scientific director of the Manhattan Project. His work in theoretical physics and his later reflections on the implications of nuclear weapons have had lasting impacts on both science and ethics in warfare. Additionally, the work of other scientists involved in the Manhattan Project, such as Enrico Fermi and Richard Feynman, was also shaped by the atomic bomb's development.
What discovery did Henry Moseley lead him to reorganize the periodic table?
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore resequenced the table by nuclear charge rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
How did Henry Moseley revise mendeleevs periodic table?
In 1914 Henry Moseley found a relationship between an element's X-ray wavelength and its atomic number (Z), and therefore rearranged the table by nuclear charge / atomic number rather than atomic weight. Before this discovery, atomic numbers were just sequential numbers based on an element's atomic weight. Moseley's discovery showed that atomic numbers had an experimentally measurable basis.
How was the periodic table first organized atomic number or atomic mass?
The periodic table was first organized by atomic mass. However, after the discovery of isotopes and inconsistencies around this method, it was later rearranged based on atomic number, which reflects the number of protons in an atom's nucleus.
State the periodic law on which Mendeleev's Periodic table was based and why and how this periodic law changed?
Mendeleev's Periodic Table was based on the periodic law which states that the properties of elements are a periodic function of their atomic masses.

This discovery changed the atomic model by replacing the plum pudding model with the planetary model, where electrons orbit a central nucleus. Rutherford proposed that the nucleus contained positively charged protons while the electrons orbited around it.
On what were the original atomic weights based?
The original atomic weights were based on the mass of hydrogen.
Why was Moseley able to resolve the discrepancies in Mendeleev's table when Mendeleev could not?
Moseley's discovery of atomic number allowed for organizing elements based on their atomic number rather than atomic weight, leading to a more accurate arrangement of elements. Mendeleev's periodic table was based on atomic weight, which resulted in discrepancies. Moseley's insight helped to resolve these discrepancies and create a more precise periodic table.
When did mosley create his periodic table?
Henry Moseley created his periodic table in 1913 by arranging elements by their atomic number, a fundamental change from the earlier practice of ordering elements by atomic weight. Moseley's work led to the modern periodic table we use today.
Which scientist discovered that the atomic number rather than the atomic weight is more responsible for the properties of an element?
Henry Moseley, a British physicist, made this discovery in 1913 through his experiments with X-ray spectra. Moseley's work led to the reorganization of the periodic table based on atomic number instead of atomic weight.
