How do alpha particles beta particles and gamma rays originate in the nucleus of the atom?

Answer 1

A beta particle is created when a neutron inside an unstable nucleus changes into a proton (or vice versa), losing energy and mass in the form of an electron (or positron), which is the beta particle.

Answer 2

An alpha particle is a helium nucleus. The symbol is 24He2+, meaning 2 protons, 2 neutrons, and no electrons. It is split off from a larger nucleus during the alpha form of radioactive decay. It is similar to fission, in that it represents splitting of the parent nucleus into two parts, though the split ratio is tilted all the way to the limit, and there is often no free neutron accompanying it.

Answer 3

Beta particles are emitted from the nucleus of a radioactive element. They have the same mass and charge as the electron (negative Beta's), and sometimes they have the same mass but opposite charge of an electron. Then they are called positrons or positive Beta's.

There is an interesting process that occurs inside a nucleus to emitt these Beta's because normally electrons and/or positrons don't exist inside a nucleus. When a radioactive element emitts a negative Beta, experiments show that the element transforms into a different element. So what happens is that a neutron inside the nucleus changes into a proton and an electron. The electron is "spit" out as what we call a Beta and the proton stays behind. Since the atom now has an extra proton it is a different element. In the case of positive Beta emission a proton changes to a neutron and a positron. The positron (positive electron) is "spit" out and the neutron stays behind. Now there is one less proton and again we have a new element.

Radioactive elements that emitt Beta's can occur naturally or they can be artificially made by bombarding a non-radioactive element with neutrons.

Answer 4

Radioactive decay of unstable nuclei:

• Alpha is a simple electrostatic ejection of 2 protons and 2 neutrons
• Beta is caused by the weak force mediating conversion of a neutron to a proton, resulting in the ejection of an electron (the beta particle) and a neutrino
• Gamma is a release of energy from an excited state by emitting a photon

Answer 5

The beta particles originate in the nucleus and electrons originate outside the nucleus.

Answer 6

The beta particle is emitted from the nucleus.

Answer 7

When the protons and neutrons in an excited unstable nucleus relax into a lower energy more stable configuration the excess energy is released as a gamma ray photon.

Answer 8

i need help i dont understand where it comes from

Answer 9

they originate in the nucleus.

Answer 10

Alpha particles come from the nucleus.
