When an unstable nucleus produces an alpha particle by how many units does the atomic number of the nucleus change?
An alpha particle is a helium nucleus, which consists of 2 protons and 2 neutrons. When an unstable nucleus emits an alpha particle, it loses 2 protons, which means its atomic number will be reduced by 2.
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.
What does An alpha particle has the same mass and atomic number as?
Helium nucleus
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.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
The nucleus of the chemical element with atomic number 2 is known as an alpha particle. It is emitted by some radioactive substances during the process of alpha decay, where a parent nucleus releases an alpha particle to become a more stable daughter nucleus. Alpha particles consist of two protons and two neutrons bound together.

An alpha has the same mass and atomic number as an?
A+. . .. . . . helium nucleus
If a radioactive nucleus with an atomic number of 88 emits an alpha particle what will the atomic number of the new nucleus be?
Two less, since the alpha particle takes away two protons.

When radium emits an alpha particle the resulting nucleus has atomic number?
The result is radon, atomic number 86. 226Ra - alpha particle = 222Rn (radon, a radioactive gas)
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.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
The nucleus of the chemical element with atomic number 2 is known as an alpha particle. It is emitted by some radioactive substances during the process of alpha decay, where a parent nucleus releases an alpha particle to become a more stable daughter nucleus. Alpha particles consist of two protons and two neutrons bound together.
When radium atomic number 88 emits an alpha particle the resulting nucleus has atomic numbers?
226Ra------------alpha particle----------222Rn (radon, a radioactive gas)
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 changes take place in the nucleus when an alpha particle is emitted?
In short, alpha radiation occurs when an unstable nucleus emits 2 protons and 2 neutrons from it's nucleus. This means that the atomic number decreases by 2 and the nucleon number decreases by 4.
