When promethium-165 atomic number 61 undergoes beta decay it transmutates into?
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.
What happens when the number of protons in an atom change?
When the number of protons in an atom changes, the identity of the element changes because the number of protons determines the element's atomic number. If the number of protons changes, the atom becomes a different element. This process is called nuclear fusion or fission.
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).
Does the element change when the atomic mass changes?
No, the element remains the same even when the atomic mass changes. Atomic mass is determined by the number of protons and neutrons in the nucleus of an atom, but changing the number of neutrons does not change the identity of the element.
Why are there not isotopes with unusual numbers of protons?
If the number of protons changes so does the element, as the number of protons defines the element.

What detemines the identit of an element?
The number of protons it has in the nucleus. Number of electrons and neutrons can vary but if the number of protons changes, you have a different element. Number of protons is a constant in an element which never changes.

Do the number of protons in a specific atom ever change?
no. because if the number of protons changes, then the element changes
Why are there not isotopes with unusual numbers of protons?
If the number of protons changes so does the element, as the number of protons defines the element.
What happens when the number of neutrons changes in a element?
a poopy
An element cannot be changed by any physical or chemical means because those changes do not affect the atom's number of neutrons.?
An element is defined by the number of protons in its nucleus, known as its atomic number. This number determines the specific properties and identity of the element. Any physical or chemical changes to an element do not alter the number of protons, and therefore do not change the element itself.
When neutrons are released from the nucleus it changes to what?
Isotopes of the element is formed when the number of neutron changes.
The atomic number is the same as?
The atomic number is the number fo protons in an atom's nucleus. It decides the element's position on the periodic table, as well as what the element is. No two elements have the same atomic number. As soon as the atomic number, or number of protons, changes, the element itself actually changes into a new element.
The part of an element that never changes is the?
The number of protons.
