Why cant electron exist in the nucleus?

Answer 1

When a nucleus is formed, the nucleons involved, that is, the protons and neutrons that are going to be forming the nucleus, are "squeezed" together in the fusion reaction. During this reaction, the stong interaction or strong nuclear force mediates the conversion of some of the mass of each proton and neutron that is going to make up the new nucleus into nuclear binding energy. The binding energy, or nuclear glue, is created from a bit of the mass of each nucleon involved through what is called mass deficit. If any electrons are present in the vicinity of the fusion reaction, they are "locked out" of the reaction by the strong interaction. The electron will not be permitted to become involved in the fusion reaction because it does not have the "right stuff" to participate. That is why no electrons can be in a nucleus. Note that in some kinds of nuclear decay called beta minus decay, an electron is created within the nuclues, and it is quickly ejected. The electron did not exist in that nucleus, but was created through the mediation of the weak interaction or weak nuclear force. A neutron was converted into a proton and an electron and an antineutrino, and then the electron was kicked out of the nucleus.

Answer 2

the answer is simple n short . the thing is that atomic nucleus or we can say that the atomic radius of the electron is bigger than the atomic radius of the nucleus itself. like a bigger thing can not fit into a smaller area like wise is the case with electrons .hence they rotate outside the nucleus. however there is an other answer according to heisenbergs uncertainty principle ....

Answer 3

Electrons don't exist in the nucleus because if it exists then it will attract towards the proton which is positively charged and the whole energy will be lost resulting the atom may collapse.

Answer 4

Diameter of the atomic nucleus is of the order of 10-15m

The maximum uncertainty in the position of electron is 10-15 m.

Mass of electron = 9.1 x 10-31 kg.

x. p = h / 4π

x x (m.v) = h/4π

v = h / 4π x 1 / x.m = 6.63 x 10-34/ 4 x (22/7) x 1 / 10-15 x 9.1 x 10-31

v = 5.80 x 1010 ms-1

This value is much higher than the velocity of light and hence not possible.

Answer 5

It does not violate any law of our Universe to have electrons inside the nucleus of an atom. However, the probability of an electron being there is quite small. When you work out a solution for the expected location of an electron in a field of atom's nucleus, you find that an electron is most likely to be found well outside the nucleus.

When an electron falls into a nucleus (a type of radioactive decay called K capture) it will combine with a proton and form a neutron. So even when an electron does enter a nucleus, it doesn't last.
