An alpha particle is composed of two protons and two neutrons, so when an atom loses an alpha particle, its mass number decreases by four. However, since the atom loses two protons, it is now a different element. It is now the element with an atomic number minus the two protons.
What else can I help you with?
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 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.
What particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
What does An alpha particle has the same mass and atomic number as?
Helium nucleus
What Atomic number is the number of what subatomic particle?
Atomic number is equal to the number of protons and electrons (in a neutral atom).

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 particle does the atomic number equal in the nucleus?
The number of Protons in the nucleus determines the atom's Atomic number.
What is proton or atomic number?
A proton is a subatomic particle in the nucleus of an atom. Protons have a positive electric charge. The atomic number of an element is equal to the number of protons in the nucleus of one of its atoms. Therefore, if you change the number of protons in an atom, you change the element.
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.
What does An alpha particle has the same mass and atomic number as?
Helium nucleus
That particle that gives an element its atomic number is in this part?
The atomic number is determined by the number of protons, which are located in the nucleus.
What subatomic particle is the same as the atomic number?
In a neutral atom, the number of protons (or the number of electrons) are the same as the atomic number.
What Atomic number is the number of what subatomic particle?
Atomic number is equal to the number of protons and electrons (in a neutral atom).
The atomic number of an element is equal to the number of contained in one atom of that particle?
The atomic number of an element is equal to the number of protons contained in the atomic nucleus.
When thorium emits beta particle the resulting nucleus has a atomic number?
The resulting element is protactinium, atomic number 91.
