Sentences with phrase «neutrons than protons»

«Think of a neutron star like it's a huge nucleus, where you have ten times more neutrons than protons.

Not exact matches

if you want hydrogen 1 proton, 1 neutron, 1 electron and you have 1 atom of hydrogen; the hard part is it would cost us more energy than we can afford at this point in our technological stage to accomplish such a feat.
Pagels (1984) points out that if the relative masses of protons and neutrons were different by a small fraction of 1 per cent, making the proton heavier than the neutron, hydrogen atoms would be unstable since the protons that constitute their nuclei would spontaneously decay into neutrons.
Protons and neutrons cluster in a nucleus, 100,000 times smaller than its atom, and are themselves composed of other stupendously small things: quarks and gluons.
Analysis of the water leaving Venus's atmosphere, however, shows that many of the hydrogen ions are actually a stable isotope of the element called deuterium, which consists of a proton and a neutron (rather than just a proton) in its nucleus.
Whereas «up» and «down» quarks instantly condense to form protons and neutrons, the addition of «strange» quarks makes a stable nugget that can grow far more massive than the nuclei of ordinary atoms, Witten proposed in 1984.
But rather than a knight getting «un-horsed,» this high - speed collision melts the protons and neutrons of the ions, freeing the quarks and other particles to disperse in an explosion very like that of the Big Bang.
The only way such a universe could create complex matter would be to have started out with fewer neutrons and more free protons than our universe did.
Because a proton or a neutron is on the order of a million times smaller than an atom, nuclear fission and fusion typically require energies on the order of millions of electron volts (MeV).
When deuterium and helium - 3 fuse, they produce high - energy protons rather than neutrons.
Why is a neutron, for example, more massive than a proton rather than the other way around?
Because the strong force holding the protons and neutrons together is stronger than the electromagnetic one, knocking the nucleus apart into pieces demands more energy than removing the electrons.
At short distances (i.e. within the nucleus), a very strong force, more powerful than electromagnetism, takes over and attracts the protons and neutrons.
Nucleons prefer pairing up with nucleons of a different type (proton preferred neutrons to other protons) by 20 to 1, and nucleons involved in a short - range correlation carry higher momentum than unpaired ones.
So the average proton momentum is going to be higher than the average neutron momentum, because it's mostly the neutrons that are sitting there, doing nothing, with nothing to pair up with, except themselves.»
The phenomenon also surprisingly allows a greater fraction of the protons than neutrons to have high momentum in these relatively neutron - rich nuclei, which is contrary to long - accepted theories of the nucleus and has implications for ultra-cold atomic gas systems and neutron stars.
Photons with a billion times more energy than photons of visible light exhibit properties once thought to belong solely to hadrons: the class of particles that includes the proton and the neutron
Baryons are particles of normal or «ordinary» matter (e.g., such as protons and neutrons) that make up more than 99.9 percent of the mass of atoms found in the cosmos.
«As already mentioned, there is no stable nucleus with five or eight nuclear particles [nucleons], so it is not possible to build nuclei heavier than helium by adding neutrons or protons to helium (4He) nuclei, or by fusing pairs of helium nuclei.
We've long known that the basic constituents of nature are far more numerous and varied than the protons, neutrons and electrons that many people first learned about in high school.
All elements heavier than iron were necessarily made by accretion of mostly neutrons but sometimes protons onto lighter nuclei.
