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.

When an unstable nucleus produces an beta particle by how many units does the atomic number of the nucleus change?

The atomic number decreases by one for each beta particle


When an unstable nucleus emits a beta particle is the atomic number increased by one unit?

Yes. When an atom emits a Bita particle, actually its the degradation of a neutral particle, i.e a neutron, which forms a proton and an electron. Since no electron can exist inside a nucleus, so it is emitted out as a bita particle, but the proton stays inside the nucleus, thereby increasing its atomic number by 1.


What atomic particle is not in the nucleus?

electrons are not present in 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 atomic number when the nucleus releases a beta particle?

When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 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.
