An alpha particle is essentially a helium atomic nucleus with 2 protons and 2 neutrons. An alpha particle decay will result in the loss of 2 protons and 2 neutrons. Because mass number is the sum of protons and neutrons, an alpha decay will reduce the mass number by 4, (and the atomic number by 2).
What else can I help you with?
What are the different types of radioactive decay and how do they differ from each other?
There are three main types of radioactive decay: alpha decay, beta decay, and gamma decay. Alpha decay involves the emission of an alpha particle, which is a helium nucleus consisting of two protons and two neutrons. This type of decay reduces the atomic number of the nucleus by 2 and the mass number by 4. Beta decay involves the emission of a beta particle, which can be either an electron (beta-minus decay) or a positron (beta-plus decay). Beta decay changes the atomic number of the nucleus by 1 but does not significantly affect the mass number. Gamma decay involves the emission of gamma rays, which are high-energy photons. Gamma decay does not change the atomic number or mass number of the nucleus but helps the nucleus reach a more stable energy state. These types of decay differ in the particles emitted and the changes they cause to the nucleus.
What is the process in which a new lighter element is created by the release of an alpha ray particle from an atomic nucleus?
This process is known as alpha decay. During alpha decay, an unstable atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This emission results in the transformation of the original nucleus into a new, lighter element with a lower atomic number.
What happens to the mass number of a nucleus when it emits an electron?
When a nucleus emits a beta particle (electron) it is a result of neutron decay. This decay will also release an antineutrino and a proton is left which increases the atomic mass by one thereby changing the element.
If Sulfur 34 undergoes alpha decay what will it become?
If Sulfur-34 undergoes alpha decay, it will become silicon-30. This is because in alpha decay, the parent nucleus loses an alpha particle (which is a helium nucleus composed of 2 protons and 2 neutrons), resulting in a new nucleus with an atomic number reduced by 2 and a mass number reduced by 4.
Larger a nucleus is the greater its?
Larger a nucleus is, the greater its atomic number and the more protons it contains. This leads to stronger nuclear forces within the nucleus and a higher tendency for radioactive decay.
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 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.
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.
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.
How does a nucleus change when beta decay of the nucleus occurs?
The atomic number increases by one unit when a beta decay occurs.
How is the atomic number of a nucleus change by gamma decay?
In gamma decay ,nucleus lose a charge of -1 and the daughter nucleus has charge of Z+1.

What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.
When an unstable magnesium nucleus undergoes gamma decay the nucleus formed is that of what?
When an unstable magnesium nucleus undergoes gamma decay, it remains as a magnesium nucleus. Gamma decay does not change the atomic number or mass number of the nucleus, only releasing a gamma photon to reduce excess energy.
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 nuclear decay processes would form a daughter nucleus with an atomic number larger than the parent nucleus?
beta
