What fact about atomic nuclei suggests the existence of the neutron?

The atom has protons in it. They are positively charged and attract and hold the electrons. But the protons are snuggled in the nucleus, and they don't like each other. Like charges repel each other. There is a moderating force present that "makes" the protons stick together in there. That's the fact that suffests something else is at work. And it is the neutron that is the nuclear building block that makes it all stick together.

What is the name of the process during which atomic nuclei decay?
D. Radioactivity
What did Maria Goeppert Mayer do?
maria mayer gave the public a great understanding of the atomic nuclei. she also figured out the magic numbers corrispondent to the nuclei
What is the atomic bomb and how do you make it less powerful?
An atomic bomb is any bomb that derives its energy from the atomic nucleus, it may do this by either the process of fission of heavy nuclei or the process of fusion of light nuclei. Atomic bombs can also be called nuclear bombs.I don't really understand what you mean by "make it less powerful". The US has made tactical atomic weapons with yields as low as 0.1KTon (100 tons TNT equivalent), however I don't know if they are still stockpiled (they are very inefficient and wasteful in their use of plutonium). For optimal efficiency in use of uranium or plutonium in pure fission atomic bombs, a yield of 200KTons to 400KTon is preferred, however I know no such bombs are still stockpiled as compact fusion bombs in this yield range and higher are both more efficient and much cheaper to build.
Where do atomic bombs get their power?
atomic bombs get there power from the energy released by splitting an atom. A nucleus is fired into an unstable isotopse such as Uranium 235 and the Uranium is split into two daughter nuclei. A cloud of electrons, along with some energy, is released. Each of the electrons in turn splits another atom, creating a large chain reaction, and this releases enough energy to power an atomic bomb.
What element was created by the first H bomb test?
Element number 99, later named Einsteinium, was discovered in the debris from the first hydrogen bomb explosion in 1952. Only a tiny number of atoms were detected, formed from the decay of neutron-bombarded californium nuclei.
Which of these is a particle in atomic nuclei?
Neutron
What is a dead star with the density of an atomic nuclei called?
neutron star
How does electron differ from a neutro?
An electron bears a negative charge, a neutron has no charge.A neutron is about 2,000 times as massive as an electron.Neutrons exist in atomic nuclei, electrons orbit nuclei.
Which British physicist discovered the existence of atomic nuclei?
Ernest Rutherford
Is a neutron a partial within an atom?
I do not know what you mean by "partial", but a neutron is a subatomic particle and neutrons can go into the make up of atomic nuclei.
When a neutron in absorbed by a U-235 nucleus what is the neutron number?
The atomic number of uranium is 92, so its atoms have 92 protons in their nuclei. If uranium-235 absorbs a neutron, it would then have the mass number of 236. The number of neutrons is the mass number minus the atomic number, so the number of neutrons in the uranium-236 nuclei would be 236-92=144.
What is a proton and neutron?
A proton is a positively charged subatomic particle found in the nuclei of atoms. The number of protons an element has in its atomic nuclei is its atomic number, and defines the element. A neutron is a subatomic particle that has no charge and is also found in the nucleus of an atom. The number of neutrons in the nuclei of an element can vary. Atoms of the same element that have different numbers of neutrons, giving them different mass numbers, are called isotopes.
What is a neutron proton?
A proton is a positively charged subatomic particle found in the nuclei of atoms. The number of protons an element has in its atomic nuclei is its atomic number, and defines the element. A neutron is a subatomic particle that has no charge and is also found in the nucleus of an atom. The number of neutrons in the nuclei of an element can vary. Atoms of the same element that have different numbers of neutrons, giving them different mass numbers, are called isotopes.
What does the fusion of hydrogen nuclei create?
Fusion of two hydrogen nuclei results in the formation of helium and a stray neutron. H31 + H21 -----> He42 + n10 The hydrogen with atomic number 3 is trituim and the hydrogen with atomic no. 2 is deutrium. They both fuse together to form Helium with the release of a spray neutron, accompanied by a large release of energy.
What determines the amount of energy an electrons has?
distance from the atomic nuclei
What happens to the protons in the atomic nuclei and the degenerate electrons that were inside the star that creates a neutron star?
The protons and electrons fuse to form neutrons.
What did james chadwick do to contribute to the atomic theory?
James Chadwick, in 1932, theorized that atomic nuclei were too light to only contain two subatomic particles , he developed the idea of a neutron , a particle with a neutral charge which accounts for the additional mass of atoms neutron have the same mass as protons
