Beta is produced by the weak nuclear force.
- n --> p + e- + v, decay to electron & antineutrino
- p --> n + e+ + v, decay to positron & neutrino
The leptons do not preexist in the nucleus, their wavelength would be too long for that.
I think you are confused when you say "contain no elements". No nucleus contains elements, the nucleus is part of an atom and atoms are part of elements & compounds.
Perhaps you meant to say "contain no electrons". If so you are right, see above. The leptons (electron, positron, neutrinos) are created by a decay process mediated by the weak nuclear force.
What else can I help you with?
Does the emission of alpha beta and gamma radiations take place from a nucleus at the same time?
No.
What is a high energy electron from the nucleus called?
beta particle In beta decay a neutron is converted into a proton, electron (also called a beta particle) and an electron antineutrino.
What are the particles called Radioactive elements release energy?
Nucleus that causes a neutron to change into a proton is called a beta particle.
What does an unstable nucleus emit?
An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
Do radioactive elements produce alpha and beta particles only?
No, radioactive elements can also produce gamma rays along with alpha and beta particles. Gamma rays are high-energy electromagnetic radiation emitted from the nucleus during nuclear decay.
Does the emission of alpha beta and gamma radiations take place from a nucleus at the same time?
No.
Which elements typically are radioactive and why?
Those elements which don't very stable nucleus tend to be radioactive.Some isotopes of elements are radioactive in nature like Tritium(an isotope of hydrogen) and isotopes of cobalt are radioactive.Apart from the isotopes, many heavier elements(most of the trans-uranium elements) are radioactive in nature.An element having unstable nuclei(generally after being formed by alpha or beta decay) tends to attain a stable nucleus by gamma decay and emits radiation in the process.All of the alpha, beta and gamma decay give out harmful radiations with gamma rays being most dangerous due to their highest penetrating power.
Which radiations are used to prevent sprouting of onions or potatoes?
beta
Are all the radiations are electro magnetic radiations?
No, not all radiation is electromagnetic radiation, though some is. Exceptions: Neutron radiation - Emission of neutrons. Alpha decay - Emission of a helium-4 nucleus (2 protons and 2 neutrons). Beta radiation - Emission of electrons.
What is a high energy electron from the nucleus called?
beta particle In beta decay a neutron is converted into a proton, electron (also called a beta particle) and an electron antineutrino.
What are the particles called Radioactive elements release energy?
Nucleus that causes a neutron to change into a proton is called a beta particle.
What are radiation rays?
Ionizing radiations are alpha, beta, gamma rays, etc.
What does an unstable nucleus emit?
An unstable nucleus (radioactive isotope) may emit: alpha particles, beta particles, gamma radiations, electrons, positrons, X-rays, and neutrons, depending on which nucleus is doing the emitting.
How many radiations are emitted by uranium?
Uranium-238 emits alpha radiation; its half-life is 4,468×109 year.
What are the uses for promethium?
Applications of promethium: - beta radiation source in instruments used to measure thickness of coatings by retrodiffusion of beta radiations - luminous paints - atomic batteries
What are the types of nuclear radiations?
Alpha, beta, and gamma are the main ones. Alpha is the ejection of alpha particles which are 2 protons plus 2 neutrons, which is a helium nucleus. Beta particles are electrons. Gamma radiation is EM radiation of very high frequency, beyond x-rays.
Do radioactive elements produce alpha and beta particles only?
No, radioactive elements can also produce gamma rays along with alpha and beta particles. Gamma rays are high-energy electromagnetic radiation emitted from the nucleus during nuclear decay.
