What is the difference in atomic number between the original isotope of uranium that begins the decay series and the final isotope of lead?
The original isotope of uranium in the decay series is uranium-238, which has an atomic number of 92. The final isotope in the decay series is lead-206, which has an atomic number of 82. Therefore, the difference in atomic number between uranium-238 and lead-206 is 10.
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 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.
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 is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.

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.
How is the atomic mass number of a nucleus changed by alpha decay or by beta decay or by gamma decay?
The mass does not change much. The Atomic number will increase though.
How does nuclear decay affect the atomic number and mass number of a nucleus that changes after undergoing decay?
Beta+ decay and electron capture causes the atomic number to drop by one. Beta- causes the the atomic number to rise by one.Proton emission causes the atomic and mass number to drop by one.Neutron emission causes the mass number to drop by one.Alpha decay causes the atomic number to drop by two and the mass number to drop by four.
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.
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.
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. =)
Does there seem to be any pattern in the eries f alpha and beta decays?
Yes, there are observable patterns in the series of alpha and beta decays. Alpha decay typically occurs in heavy and unstable nuclei, leading to a reduction in atomic mass and a change in atomic number by two. In contrast, beta decay involves the transformation of a neutron into a proton (beta-minus) or a proton into a neutron (beta-plus), resulting in an increase or decrease in atomic number by one. These decay processes often lead to the formation of daughter isotopes, which may continue to decay, creating a decay series that eventually stabilizes into non-radioactive elements.
In alpha decay is the atomic number of the daughter nucleus equal to the atomic number of the isotope undergoing decay?
No, in alpha decay the atomic number of the daughter nucleus is decreased by 2 and the mass number is decreased by 4 compared to the isotope undergoing decay. This is because an alpha particle (helium nucleus) is emitted during alpha decay, resulting in a new daughter nucleus with a lower atomic and mass number.
