The process in which a new lighter element is created by the release of an alpha ray particle from an atomic nucleus is called alpha decay of the original nucleus.

What particle of an element cannot be created or destroyed?
The number of protons in the nucleus. This determines the chemical properties of the atom and which chemical element it is.
The particle NOT found in the nucleus of the atom is what?
The particle not found in the nucleus is the electron
What subatomic particle number determines the identity of an element?
The number of protons, which is the atomic number of an element, determines the identity of an element.
Is a nucleus a particle?
No, the nucleus itself is not a particle. It is made up of protons and neutrons, which are subatomic particles.
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.
Are the alpha particle and helium nucleus the same thing?
Yes and no, alpha particles are a form or radiation (a helium nucleus), they are emitted from an unstable radioactive element which decays (and turns into some lighter element) by emitting the alpha particle. This form of decay is called alpha decay.
How do the atomic number change?
The atomic number of an element is FIXED it can not normally be changed. However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
Nucleus of the chemical element atomic number 2 emitted by some radioactive substances?
alpha particle, He nucleus
What element has the same number of protons and neutrons in its nucleus as an alpha particle?
An alpha particle has 2 protons and 2 neutrons. That is the same as a helium nucleus.
What will happen inside the nucleus if there alpha particle radiation?
Two neutrons and two protons will split off from the main nucleus as the alpha particle, leaving a different element.
What is the definition of radioisotopes?
A radioactive isotope of an element
Which subatomic particle identifies an atom as that of particular element?
The number of protons defines the element.
The atomic number is the number of what in an element?
An element's atomic number is a count of how many protons are normally part of the element's nucleus. Since protons are normally the only particle in the nucleus with a charge (+), the atomic number also represents the charge of the nucleus.
What is radioactive decay with Earth's crust?
When a radioactive isotope of an element releases a radiation particle the sub-atomic structure of it's nucleus changes. If an alpha particle is released the nucleus loses 2 protons and 2 neutrons, making it a new, lighter and smaller atom and therefore a different element. If a beta particle is released one of the neutrons in the nucleus releases an electron and becomes a proton so the atom's mass does not change significantly but t does become a different element.
What is the elements neutron?
A neutron is not an element it is a subatomic particle.
What particle defines an element?
The number of protons in an atom's nucleus determines the identity of element. The number of protons equals the atomic number.
What is fission in physics?
In physics, fission is the process in which a heavy, unstable element is split into two lighter elements by bombarding it with a small particle. Some of the energy that was binding the element's nucleus together is then released, along with a third, tiny particle that is released as well. The tiny particle then collides with another of the heavy elements, causing it to split as well, emitting another particle which collides with another heavy element, and so on. This is the chain reaction that allows for sustainable nuclear power generation, in which the reaction is controlled, or the detonation of nuclear weapons, in which the reaction is uncontrolled.
