In beta minus decay (as opposed to beta plus decay), the ejected electron will leave the nucleus and the decay event at fairly high kinetic energy. The actual energy will depend on which atom underwent the beta decay. That means there are a range of energies possible. This electron will scatter (collide) and lose energy, and then, having lost much of its kinetic energy, it will just end up "adrift" as a static charge, and finally it will go to ground.
i neutron is converted into one proton by the emission of one electron. Since the electron cannot stay in or near the nucleus it moves away at the speed of around 10 to the power 8 m/s. The atom moves up by one place in the Periodic Table. Eg- if a atom has 83 protons and 85 neutrons after beta emission it will have 84 protons and 84 neutrons. 1 electron would be emitted.

Do allpha beta and gamma rays come from same element?
No, alpha, beta, and gamma rays are not all produced by the same element. Alpha particles consist of two protons and two neutrons and are emitted during radioactive decay of heavy elements like uranium. Beta particles are electrons or positrons emitted during the decay of certain isotopes. Gamma rays are high-energy photons emitted during the transition of a nucleus to a lower energy state and are not particles.
How many protons are in a radioisotope?
The most common type of beta-decay is beta-negative decay. A neutron decomposes to a proton, an electron, and an anti-neutrino. This involves one proton.
Why energy of beta particles is different in beta particle decay?
The energy of beta particles in beta decay is not fixed because it depends on the specific isotope and decay process involved. Beta decay can produce high-energy electrons and positrons through beta minus and beta plus decay, respectively. The energy of the beta particles is determined by the energy released during the decay process.
What happens when an atom releases both an alpha and a beta particle?
When an atom releases both an alpha and a beta particle, it transforms into a different element with a lower atomic number. This process is known as double beta decay. The atom undergoes nuclear transmutation to achieve a more stable configuration.
How does an isotope of an element change during nuclear decay?
During nuclear decay, an isotope of an element changes by emitting radiation, such as alpha or beta particles, or gamma rays. This process results in the isotope transforming into a different element or a different isotope of the same element. The change is necessary to achieve a more stable configuration, typically by adjusting the number of protons and neutrons in the nucleus.
What new element is then created by a single beta decay of this isotope 239U?
In a single beta decay of uranium-239 (239U), the new element created is neptunium-239 (239Np). During the beta decay process, a neutron in the uranium nucleus is transformed into a proton, resulting in the creation of neptunium-239.
Do element identities reamin the same or change during nuclear decay?
That depends on the nuclear decay type. For gamma decay, the identity does NOT change, but for alpha and beta, it does.
Do allpha beta and gamma rays come from same element?
No, alpha, beta, and gamma rays are not all produced by the same element. Alpha particles consist of two protons and two neutrons and are emitted during radioactive decay of heavy elements like uranium. Beta particles are electrons or positrons emitted during the decay of certain isotopes. Gamma rays are high-energy photons emitted during the transition of a nucleus to a lower energy state and are not particles.
What happens to the total number of nucleons during beta decay?
The total number of nucleons remains the same during beta decay. A neutron is converted into a proton and an electron (beta particle), so the total number of nucleons (protons + neutrons) stays constant.
How many protons are in a radioisotope?
The most common type of beta-decay is beta-negative decay. A neutron decomposes to a proton, an electron, and an anti-neutrino. This involves one proton.
What is the daughter product in the beta decay of 144Ce?
The daughter product in the beta decay of 144Ce is 144Pr, which stands for promethium. Promethium is a radioactive element that forms as a result of the beta decay of cerium-144.
What radiation is emitted during beta decay?
During beta decay, a beta particle (an electron or positron) is emitted, along with an antineutrino or neutrino, depending on whether it's beta-minus or beta-plus decay, respectively. Beta decay involves the transmutation of a neutron into a proton within the nucleus, releasing the beta particle in the process.
What is emitted during beta decay?
During beta decay, a beta particle (either an electron or a positron) is emitted from the nucleus of an atom. This emission occurs when a neutron in the nucleus is transformed into a proton, with the accompanying release of a beta particle and an antineutrino (in the case of beta-minus decay) or a neutrino (in the case of beta-plus decay).
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
How is it possible for an element to decay forward in the periodic table that is to decay to an element of higher atomic number?
An element can decay forward in the periodic table through processes like beta decay, where a neutron in the nucleus is converted into a proton, increasing the atomic number by one. This transformation results in the emission of an electron (beta particle) and an antineutrino. By changing a neutron into a proton, the element transmutes into an element with a higher atomic number.
If The parent element decays by beta decay. Which daughter element will form?
If the parent element undergoes beta decay, it will transform into a daughter element with an atomic number that is one greater than the parent element. This occurs when a neutron in the nucleus is transformed into a proton, releasing an electron (beta particle) and an antineutrino.
In alpha and beta decay the parent elements is always a different element from the daughter element?
