This is emission of an alpha particle which is a helium nucleus. Thus the atomic number decreases by two and the atomic weight by four, in such a radioactive decay

Which part of atom take part in nuclear reaction?

The nucleus of an atom is the part that takes part in nuclear reactions. It consists of protons and neutrons, which are involved in processes such as fission and fusion. The electrons surrounding the nucleus are not typically involved in nuclear reactions.


A reaction in which small nuclei combine to form a heavier nucleus?

This is a nuclear fusion reaction, where two or more small atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This type of reaction is the process that powers the sun and other stars.


What is fissile nucleus?

A fissile nucleus is an atomic nucleus that is capable of undergoing fission when bombarded by neutrons. This process releases a large amount of energy, making fissile nuclei important for nuclear reactors and nuclear weapons. Examples of fissile nuclei include uranium-235 and plutonium-239.


Which nuclear reaction occurs when one nucleus splits into two nuclei?

Nuclear Fission


Whats the nuclear reaction of fission?

The splitting of a nucleus atom


When a uranium nucleus breaks into fragments what type of nuclear reaction occurs?

In nuclear physics and nuclear chemistry, nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts (lighter nuclei), often producing free neutrons and photons (in the form of gamma rays).


Does the explosion in a nuclear bomb count as a rapid chemical reaction?

No, a nuclear bomb involves a nuclear chain-reaction.A chemical reaction involves the orbiting electrons in an atom.A nuclear reaction involves the nucleus (hence "Nuclear") of an atom.


What is the most common nuclear reaction?

The most common nuclear reaction is nuclear fusion, where atoms combine to form a heavier nucleus. This reaction is what powers the sun and other stars, as well as hydrogen bombs.


What is shot at an isotope's nucleus to trigger a nuclear chain reaction?

neutrons


What is shot at isotope's nucleus to trigger nuclear chain reaction?

Neutrons are typically shot at an isotope's nucleus to trigger a nuclear chain reaction. When a neutron collides with a nucleus, it can cause the nucleus to split, releasing more neutrons that can trigger additional fission reactions in nearby nuclei, leading to a chain reaction.


What type of nuclear reaction involves one nucleus breaking into multiple nuclei?

Nuclear fission is the type of nuclear reaction where one nucleus breaks into multiple smaller nuclei. This process typically releases a large amount of energy and is the basis of nuclear power plants and nuclear weapons.


When a uranium nucleus breaks up into fragments which type of nuclear reaction occurs?

The nuclear reaction that occurs when a uranium nucleus breaks up into fragments is called nuclear fission. It releases a large amount of energy in the form of heat and radiation.
