why proton lives in nucleus, not electron?

Question

sciiiiiiiiiii

Answer 1

Frist of all if protons r present in the electrons then the electrons would become neutral....Electrons can revolve and has -ve charge bcoz of the +ve protons embeded nucleus....And also the properties of both of them differ like the protons r 1836 times larger than that of electrons.......On the whole an atom can be stable only if the electrons and protons are not together.....

Answer 2

In physics, the proton (Greek πρῶτον proton = first) is a subatomic particle with an electric charge of one positive fundamental unit (1.602 × 10−19 coulomb), a diameter of about 1.5×10−15 m, and a mass of 938.27231(28) MeV/c2 (1.6726 × 10−27 kg), 1.007 276 466 88(13) amu or about 1836 times the mass of an electron.

Protons are spin-1/2 fermions and are composed of three quarks, making them baryons. The two up quarks and one down quark of the proton are also held together by the strong nuclear force, mediated by gluons.

Protons and neutrons are both nucleons, which may be bound by the nuclear force into atomic nuclei. The most common isotope of the hydrogen atom is a single proton (it contains no neutrons). The nuclei of other atoms are composed of various numbers of protons and neutrons. The number of protons in the nucleus determines the chemical properties of the atom and which chemical element it is.

Stability

The proton is observed to be stable. However, protons are known to transform into neutrons through the process of electron capture. This process does not occur spontaneously but only when energy is supplied.

\mathrm{p}^+ + \mathrm{e}^- \rightarrow\mathrm{n} + {\nu}_e \,

The process is reversible: neutrons can convert back to protons through beta decay, a common form of radioactive decay.

Grand unified theories generally predict that proton decay should take place, although experiments so far have only resulted in a lower limit of 1035 years for the proton's lifetime.

[edit] In chemistry

In chemistry and biochemistry, the proton is thought of as the hydrogen ion, denoted H+. In this context, a proton donor is an acid and a proton acceptor is a base (see acid-base reaction theories).

Answer 3

Because protons are baryons and electrons are leptons.

Baryons interact via the strong nuclear force (or more strictly the residual colour force that exists between the quarks of which they are composed), and so can be bound in the nucleus.

Electrons have no internal structure and so do not interact via the strong force. Hence they cannot be bound.

Answer 4

Electrons can not be present in nucleus because velocity of electrons is greater than velocity of light so it can't withstand in nucleus..
This reason can be explained by uncertainty principle.....
size of the nucleus is 10^-15, plancks constant is 6.6x10^-34, mass of electron is 9.1x10^-31.
By putting all these values in unceratinty fomula, we will get velocity of electrons in the range 5.524x10^12 , which is much greater than velocity of electrons and thus electrons can not be present in nucleus

Answer 5

since the protons are heavy(atomic weight) compared to electrons the nuclear force acting on it is more hence it is pulled in the nucleus...since electrons are lighter, these revolve around the nucleus due to less nuclear force existing between them

Answer 6

Simply put, its because theres a force known as the strong force which holds together a neucleus. Only particles known as gluons experience this force (protons and neutrons) not electrons so they can never be part of a neucleus.

Answer 7

if electrons and protons both stay in the nucleus then they wont be able to retain thier charges or they will fuse or burst (un stable)

Answer 8

Because Proton have thousands time bigger mass than electron.

Answer 9

No. Even protons and neutrons are produced from even smaller components. those are suggested as quarks. distinctive preparations of this up quarks and down quarks make up protons and nuetrons. we expect of that even those could be produced from even smallers components suggested as strings..
