What particle does argon 39 atomic number 18 emit when it decays to potassium 39 atomic number 19?
Argon-39 undergoes beta decay to become potassium-39, emitting an electron (beta particle) in the process. The atomic number increases by one due to the conversion of a neutron into a proton during beta decay.
What is emitted from the nucleus during beta decay?
During beta decay, a neutron is converted into a proton, releasing an electron (beta particle) and an antineutrino from the nucleus. The beta particle is emitted as the neutron decays into a proton, increasing the atomic number of the nucleus.
What happens to the atomic number of an element if it emits 1 alpha particle and 3 beta particles?
If an element emits 1 alpha particle (which consists of 2 protons and 2 neutrons) and 3 beta particles (which are electrons), the atomic number decreases by 2 due to the loss of 2 protons with the alpha decay, and increases by 3 due to the addition of 3 electrons with the beta decay. The overall effect is a decrease in the atomic number by 2.
Which particle is associated with beta decay?
The atomic nucleus can emit beta particles (beta radiation). A neutron emits a beta particle when it decays into a proton, and anti-neutrino, and an electron (which becomes the beta particle).
When a radioactive isotope emits a its atomic number increases?
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
