helium
A helium nucleus is formed from four protons.
Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
The radioactive alpha particle has the same structure as the atomic nucleus of helium. They are usually formed and emitted during alpha decay.
Protons and neutrons are the main subatomic particles in the nucleus.
A nuclear change -- involves changes in nuclear structure, such as fission (splitting) of a nucleus or an atom, or fusion (combining) of neutrons and protons to form heavier atoms. This involves about 1,000,000 times as much energy as a chemical change. And also a nuclear reactor is a device to initiate and control a sustained nuclear chain reaction. The most common use of nuclear reactors is for the generation of electrical power (see Nuclear power) and for the power in some ships (see nuclear marine propulsion). This is usually accomplished by methods that involve using heat from the nuclear reaction to power steam turbines. There are also other less common uses as discussed below. All nuclear reactors are devices designed to maintain a chain reactionproducing a steady flow of neutrons generated by the fission of heavy nuclei. They are, however, differentiated either by their purpose or by their design features. In terms of purpose, they are either research reactors or power reactors.
A helium nucleus is formed from four protons.
The helium nucleus is formed during the proton-proton reaction by the fusion of four protons. Two of the protons are converted to neutrons by the weak interaction.
During nuclear division and the process of metabolic activities ,some waste materials are formed in the nucleus. it is called nuclear waste.
Mass that is "lost" durning nuclear fusion is converted into binding energy to hold the newly formed atomic nucleus together. The lost mass, which is termed mass deficit, means the nucleus of the newly formed atom has less mass than the sum of the masses of the protons and neutrons that make up that nucleus. The stong reaction (strong nuclear force) participitates in the fursion reaction by mediating the conversion of mass into nuclear binding energy (or nuclear glue).It converts into the energy that is the desired end product of the reaction.
In a nuclear reaction, the nucleus of an atom undergoes a change. Common examples would be alpha decay, beta decay, fusion, and fusion. In each of those cases, different elements are formed in the process. This never happens in ordinary chemical reactions. In chemical reactions, it is the electrons that are involved , not the nucleus of the atom.
The nuclear reaction is: 23892U + n-------23992U-------23993Np
a nuclear recation is formed
The new substances formed during a chemical reaction are called Products.
The nuclear membrane breaks down during prophase, while the Deoxyribonucleic Acid (DNA) The nuclear membrane must break down to allow the chromosomes to be pulled apart and away from the area of the former nucleus towards the pole where the daughter cell will be formed. If the nuclear membrane did not break down the spindle fibers would not be able to reach the chromosomes and they would not be moved towards opposite poles of the cell.
AnswerNuclear reactions involve changes in the nucleus of atoms -- the number of protons and/or neutrons is changed. Chemical reactions do not cause any changes at all in the nucleus. Instead, in a chemical reaction, the electron clouds of atoms are interacting, and all changes are occurring with the electrons that surround the nucleus.

Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
