Neutron,protron?

Answer 1

Neutron is down down up, and proton is down up up quarks?
Neutrons and protons make up the nucleus of atoms?
Isolated neutron will decay into a proton by releasing an electron (beta decay) with a half life of 10.3 minutes?

I think you need to be a bit more explicit with your question, here...

Answer 2

first of all i will tell u about atom
atom is the smallest particle of an element which consist of three fundamental particle known as electron, proton, and neutron
neutron : - it is the neutral, means no charge.
electron: - it have negative charge particle and revolve around the nucleus.
proton: - it is the positive charge particle in the nucleus

nucleus: - it is the centre of the atom. in which proton and neutron are present.
proton + neutron = mass

atom is also neutral

Answer 3

neutron and protons make up the nucleus of the atom.
the neutron has a neutral charge while protons have a positive charge. they together will = the mass of the atom. the number of each does not have to be the same.

Answer 4

NEUTRON AND PROTONS ARE THE VERY SMALL PARTICLES PRESENT IN IHE ATOMS......
NEUTRONS ARE NEUTRALY CHARGED PARTICLES WHICH IS PRESENT IN THE NUCLEUS OF THE ATOM ALONG WITH THE PROTONS......
PROTONS ARE THE POSITIVELY CHARGED PARTICLES WHICH IS ALSO PRESENT INSIDE THE NUCLEUS
MANY THEORIES HAVE BEEN GIVEN BY THE SCIENTISTS OF HOW THESE TWO PARTICLES ARE HELD TOGETHER EVENTHOUGH THEY WERE NOT THE UNLIKE CHARGED SPECIES...... THEY MAY BE HELD TOGETHER BY SOME FORCES BINDING THEM TOGETHER......
BUT WHAT SO EVER,THEY TEACHES US THAT PEOPLE FROM DIFFERENT RELIGION,HABITS,CULTURE,COUNTRY CAN BE BINDED TOGETHER BY ONE FORCE CALLED"HUMANITY'

Answer 5

True low angle scattering: the incident neutron is scattered in the same direction
Apparent high angle scattering: the incident neutron is scattered in the opposite direction (from right to

Answer 6

neutron is a neutral particle in the nucleus of the atom, and a proton is a postivley chared partice in the nucleus of an atom. The element of an atom depend on the number of protons in its nucleus, and the isotope of an element depends on the number of nuetrons in its nucleus.

Answer 7

neutron and proton are found inside the nucleas. protons are positively charged particals. neutrons are neutraly charged. that binds all the postively charged protons together.thus proton stay in the nucleus.

Answer 8

they are both in the nucleus of an atom
a neutron is neutrally charged (it does not have a charge)
a proton is positively charged
they are stuck together

Answer 9

Answer 10

Neutron-

An elementary particle having approximately the same mass as the proton but lacking a net electric charge. It is indispensable in the structure of the elements, and in the free state it is an important reactant in nuclear research and the propagating agent of fission chain reactions.

Neutrons and protons are the constituents of atomic nuclei. The number of protons in the nucleus determines the chemical nature of an atom, but without neutrons it would be impossible for two or more protons to exist stably together within nuclear dimensions. The protons, being positively charged, repel one another by virtue of their electrostatic interactions. The presence of neutrons weakens the electrostatic repulsion, without weakening the nuclear forces of cohesion. In light nuclei the resulting balanced, stable configurations contain protons and neutrons in almost equal numbers, but in heavier elements the neutrons outnumber the protons; in 238U, for example, 146 neutrons are joined with 92 protons. Only one nucleus, 1H, contains no neutrons. For a given number of protons, neutrons in several different numbers within a restricted range often yield nuclear stability—and hence the isotopes of an element.

Free neutrons have to be generated from nuclei, and since they are bound therein by cohesive forces, an amount of energy equal to the binding energy must be expended to get them out. Nuclear machines, such as cyclotrons and electrostatic generators, induce many nuclear reactions when their ion beams strike target material. Some of these reactions release neutrons, and these machines are sources of high neutron flux. Neutrons are released in the act of fission, and nuclear reactors are unexcelled as intense neutron sources.

Having no electric charge, neutrons interact so slightly with atomic electrons in matter that energy loss by ionization and atomic excitation is essentially absent. Consequently they are vastly more penetrating than charged particles of the same energy. The main energy-loss mechanism occurs when they strike nuclei. As with billiard balls, the most efficient slowing-down occurs when the bodies that are struck in an elastic collision have the same mass as the moving bodies; hence the most efficient neutron moderator is hydrogen, followed by other light elements: deuterium, beryllium, and carbon. The great penetrating power of neutrons imposes severe shielding problems for reactors and other nuclear machines, and it is necessary to provide walls, usually of concrete, several feet in thickness to protect personnel.

Proton-

A positively charged particle that is the nucleus of the lightest chemical element, hydrogen. The hydrogen atom consists of a proton as the nucleus, to which a single negatively charged electron is bound by an attractive electrical force (since opposite charges attract). The proton is about 1836 times heavier than the electron, so that the proton constitutes almost the entire mass of the hydrogen atom. Most of the interior of the atom is empty space, since the sizes of the proton and the electron are very small compared to the size of the atom.

For chemical elements heavier than hydrogen, the nucleus can be thought of as a tightly bound system of Z protons and N neutrons. An electrically neutral atom will then have Z electrons bound comparatively loosely in orbits outside the nucleus.

It is instructive to contrast the proton's properties with those of the electron. All of the electron's properties have been found to be those expected of a spin-½ particle which is described by the Dirac equation of quantum mechanics. Such a Dirac particle has no internal size or structure.

By contrast, although it also has a spin of ½, the proton's magnetic moment, which is different from that for a Dirac particle, and its binding with neutrons into nuclei strongly suggest that it has some kind of internal structure, rather than being a point particle. Two different kinds of high-energy physics experiments have been used to study the internal structure of the proton. An example of the first type of experiment is the scattering of high-energy electrons, above say 1 GeV, from a target of protons. The angular pattern and energy distribution of the scattered electrons give direct information about the size and structure of the proton. The second type of high-energy experiment involves the production and study of excited states of the proton, often called baryonic resonances. It has been found that the spectrum of higher-mass states which are produced in high-energy collisions follows a definite pattern.

An important class of fundamental theories, called grand unification theories (GUTs), makes the prediction that the proton will decay. The predicted lifetime of the proton is very long, about 1030 years or more—which is some 1020 times longer than the age of the universe—but this predicted rate of proton decay may be detectable in practical experiments. See also Grand unification theories.

If the proton is observed to decay, this new interaction will also have profound consequences for understanding of cosmology. The very early times of the big bang (about 10?30 s) are characterized by energies so high that the same grand unified interaction which would allow proton decay would also completely determine the subsequent evolution of the universe. This could then explain the remarkable astrophysical observation that the universe appears to contain only matter and not an equal amount of antimatter..
