In beta- decay, a neutron changes into a proton, so the atomic number goes up by one and the Atomic Mass number does not change.
In beta+ decay, a proton changes into a neutron, so the atomic number goes down by one and the atomic mass number does not change.
In alpha decay, two protons and two neutrons are lost, so the atomic number goes down by two, and the atomic mass number goes down by four.
In neutron emission, the atomic number stays the same and the atomic mass number goes down by one. (This is rare)
In proton emission, the atomic number goes down by one and the atomic mass number also goes down by one. (This is also rare)
In spontaneous fission, you need to know the daughter product, because it is not necessarily deterministic what you are going to get.
What else can I help you with?
How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.
What happens to the atomic mass number in a radioactive substance?
In a radioactive substance, the atomic mass number may change as a result of radioactive decay. During radioactive decay, radioactive atoms undergo nuclear reactions, which can lead to the emission of radioactive particles such as alpha or beta particles. These emitted particles can cause a change in the number of protons and neutrons in the nucleus, resulting in a different atomic mass number for the resulting atom or isotope.
What is the radioactive decay of an atom resulting in the decrease in the atomic number with no charge in the atomic mass called?
It is called beta decay. there are two types: 1) posive beta decay in which atomic number decreases. 2) negative beta decay in which atomic number increases.
What element continue to decay until they finally become stable?
All elements above the atomic number of 83 are radioactive, but two elements that are under it are also radioactive. They are technetium (atomic number 43) and promethium (atomic number 61). Radioactive elements are elements that decay until stable. =)
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
Can the atomic number change over time?
No. The atomic number of an element never changes. It is the number of protons and it defines the element. In certain types of radioactive decay, the number of protons can change, but then it is no longer the same (parent) element, but rather is a new (daughter) element.
How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.

What radioactive decay processes do not reduce the atomic number of a nuclide?
Isomeric transition and internal conversion are examples of radioactive decay processes that do not reduce the atomic number of a nuclide. These processes involve the reorganization of the nucleus rather than changing the number of protons in the atom.
What is the change in atomic number after an alpha decay event occurs?
The change in atomic number after an alpha decay event occurs is a decrease of 2.
How is the atomic number of a nucleus change is it by alpha decay or beta decay or gamma decay?
Alpha decay decreases the atomic number by two. Beta- decay increases the atomic number by one. Beta+ decay decreases the atomic number by one. Gamma decay does not change the atomic number. However, gamma decay is often incidental to a precipitating alpha or beta event that upsets the energy equilibrium in the nucleus, so the two are not unrelated.
What type of radioactive decay causes the radionuclide to become an element with a higher atomic number?
Alpha decay is the type of radioactive decay that causes the radionuclide to become an element with a higher atomic number. In alpha decay, the radionuclide emits an alpha particle, which consists of two protons and two neutrons, resulting in the formation of a new element with a higher atomic number.
Is radioactive decay the same as organic decay?
No, radioactive decay is not the same as organic decay. The basic difference between radioactive decay and organic decay is that in organic decay, chemical compounds break down and the biochemical structure of the subject changes. This is a natural process that any biological structures will undergo, or it could be induced. In either case, it represents a chemical change. In radioactive decay, the actual atomic nuclei of atoms will break down in some way, depending on the substance being considered. It is the unstable atomic nucleus of given isotopes of elements that undergoes the change, and this is a nuclear or atomic change.
Does Gamma decay change the atomic number?
No, gamma decay does not change the atomic number of an atom. Gamma decay involves the release of high-energy electromagnetic radiation (gamma rays) from the nucleus of an atom, but it does not affect the number of protons in the nucleus, which determines the atomic number.
How does the atomic number of a nucleus change when beta decay occurs?
The atomic number increases by one unit when a beta decay occurs.
