When promethium-165 (Pm-165), which has an atomic number of 61, undergoes beta decay, it transmutates into neodymium-165 (Nd-165), which has an atomic number of 60. In this process, a neutron in the promethium nucleus is converted into a proton, emitting a beta particle (an electron) and an antineutrino. This results in an increase in the atomic number by one, changing the element to neodymium while the mass number remains the same.

When xenon-152 undergoes alpha decay it transmutates into what?
When xenon-152 undergoes alpha decay, it transmutates into tellurium-148. During this process, it emits an alpha particle, which consists of two protons and two neutrons, leading to a decrease in its atomic number and mass number. As a result, the atomic number decreases from 54 (xenon) to 52 (tellurium).
When an element transmutates the number of changes?
When an element transmutates, its number of protons change, which in turn changes its atomic number and chemical properties. These changes can result in the formation of a different element with different physical and chemical characteristics.
What element name symbol atomic number and ass number undergoes rusting?
Iron (symbol Fe, atomic number 26) is subject to corrosion.
If i have Barium with an atomic number of 56 and an atomic mass of 137 and it undergoes alpha decay once and then beta minus decay what is my finishing atomic number and mass?
When barium (atomic number 56) undergoes alpha decay, it loses 2 protons and 2 neutrons, resulting in an atomic number of 54 and an atomic mass of 133 (56 - 2 = 54, 137 - 4 = 133). After that, during beta minus decay, a neutron is converted into a proton, which increases the atomic number by 1, leading to an atomic number of 55 while the atomic mass remains 133. Therefore, the final atomic number is 55 and the atomic mass is 133.
What happens when Fr-223 undergoes alpha decay?
When Fr-223 undergoes alpha decay, it emits an alpha particle consisting of two protons and two neutrons. This transforms the nucleus into a different element with atomic number decreased by 2 and atomic mass number decreased by 4.

Is an atomic number always equal to the number of protons?
Yes, it is. The type of atom is defined by the atomic number. Usually, when an atom undergoes a chemical reaction, only the sharing/possession of electrons changes, and the number of protons (and so the atomic number of the element) stays the same. When an atom somehow undergoes a nuclear reaction, which is possible, the number of protons sometimes do change, but in that case the atomic number (and thus the element type) becomes different as well.
If an isotope undergoes beta emission?
If an isotope undergoes beta emission, a neutron in the nucleus is transformed into a proton, along with the emission of a beta particle (an electron) and an antineutrino. This process increases the atomic number of the nucleus by one but leaves the mass number unchanged.
What is the atomic number of a thorium atom that forms when 238 92U undergoes alpha decay?
It is 90.
What happens when Fr-223 undergoes alpha decay?
When Fr-223 undergoes alpha decay, it emits an alpha particle consisting of two protons and two neutrons. This transforms the nucleus into a different element with atomic number decreased by 2 and atomic mass number decreased by 4.
What happens to the mass number when it undergoes beta decay?
nothing, but another isotope with the same atomic mass is formed
When an unstable krypton nucleus undergoes beta decay the nucleus formed is that of?
When an unstable krypton nucleus undergoes beta decay, it transforms into a stable rubidium nucleus. In beta decay, a neutron in the krypton nucleus is converted into a proton, resulting in an increase of one atomic number while the mass number remains unchanged. This process changes the element from krypton (atomic number 36) to rubidium (atomic number 37).
What happens to the atomic number of an atom undergoing alpha decay?
The atomic number of an atom undergoing alpha decay decreases by 2. Not asked, but answered for completeness, the atomic mass number decreases by 4.
Protactinium with 91 protons and a mass of 234 undergoes alpha decay and becomes what with an atomic number of what and an atomic mass of what?
It would be actinium with 89 protons and a mass of 230.
