What happens when thorium emits a beta particle?
Thorium emits a beta particle….Section 24.1 Nuclear Radiation.
| Chemical | Nuclear |
|---|---|
| Atoms remain unchanged – may be rearranged or ionized | Atoms often changed into atoms of new element |
| Involve only valence electrons | May involve protons, neutrons, & electrons |
| Small energy changes | Large energy changes |
When a nucleus emits a beta particle its atomic number *?
When a nucleus emits a beta particle, these changes happen: the atomic number increases by 1.
When thorium atomic 90 emits a beta particle The resulting nucleus has atomic number?
When thorium decays by emitting a beta particle, what is the atomic number of the resulting nucleus? 91 protons. A beta particle is an electron, so the atomic number of the resulting nucleus is increased by 1 proton. The resulting element has 91 protons, Protactinium.
What is the atomic number of thorium?
90
Thorium/Atomic number
When the hydrogen isotope tritium 3 emits a beta particle it becomes an isotope of quizlet?
a proton is transformed to a neutron. a proton is ejected from the nucleus. a neutron is ejected from the nucleus. When tritium, 31H, decays, it emits a beta particle and becomes 32He.
When thorium-234 undergoes beta decay What other product is formed?
uranium-234
In this beta decay, a thorium-234 nucleus has one more proton than the original nucleus. In this beta decay, a thorium-234 nucleus has become a protactinium-234 nucleus. Protactinium-234 is also a beta emitter and produces uranium-234.
What change in atomic number occurs when a nucleus emits an alpha particle a beta particle quizlet?
-When a nucleus emits an alpha particle, the atomic number decreases by 2. -For emission of a beta particle, the atomic number increases by 1. -For gamma emission, there is no change in atomic number.
