Atomic mass is conserved. Atomic number is NOT typically conserved in nuclear reactions. For example, when U235 spits out an alpha particle, its number drops by two (loss of two protons), and the mass by four, resulting in Thorium 231. The total mass is conserved, because the mass of the emitted alpha particle is 4.When an element decays by beta particle emission, the atomic number goes up by one, but the mass remains essentially the same. In spontaneous fission a pair of atoms reform with a spray of free neutrons. These neutrons have a half life of almost 15 minutes. If they bombard sufficiently heavy neighboring nuclei, what occurs is known as a fission chain reaction.

What stage of mitosis is characterized by the disintegration of mitotic spindles and the formation of two new nuclear membranes?

Telophase is the stage of mitosis characterized by the disintegration of mitotic spindles and the formation of two new nuclear membranes around the two sets of separated chromosomes. During telophase, the chromosomes begin to decondense and the cell prepares for cytokinesis, where the cytoplasm divides to form two daughter cells.


Is is possible to convert atoms of one element into atoms of another?

According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).


Why are neutrons used as nuclear bullets to cause nuclear disintegration of an unstable nucleus?

Neutrons have no charge. As a result, they are not deflected by the positive charge of the nucleus or the negative charge of the electron cloud. They have the best chance of interacting with the nucleus and further destabilizing it, causing it to split.


What always stays the same when a nuclear reaction takes place?

In a nuclear reaction, the total number of nucleons (protons and neutrons) in the system remains constant, adhering to the law of conservation of mass-energy. While the identity of the elements and the arrangement of nucleons may change, the overall mass-energy before and after the reaction is conserved according to Einstein's equation (E=mc^2). Additionally, the total charge is also conserved during the reaction.


Is neutron number conserved in radioactive decay?

Neutron number is not conserved in radioactive decay processes. During beta decay, a neutron may convert into a proton, an electron (beta particle), and an antineutrino. This results in a change in neutron number.

In a nuclear disintegration the particle that is ejected may be?

It is smaller than the original atom and is possibly radioactive.


What is ejected in a nuclear disintegration?

It can eject anything, depending on the particular nucleus and the reaction involved, ranging from alpha (Helium nucleus) to beta (electron or positron), gamma (photon/energy) to neutron. If it splits, then it can "eject", so to speak, mixed fission byproducts, which encompasses a wide range of nuclei.


How is mass conserved during the process of photosynthesis?

During photosynthesis, plants use carbon dioxide from the air and water from the soil to produce glucose and oxygen. The mass of the carbon atoms from the carbon dioxide that gets converted into glucose is conserved. Therefore, overall mass is conserved during photosynthesis by following the law of conservation of mass.


What is conserved when one balances a chemical equation?

When balancing a chemical equation, the number of each type of atom on the reactant side must be equal to the number of each type of atom on the product side. Mass and charge are conserved during a chemical reaction as well.


How block disintegration take place?

block disintegration takes place by temperature differentiation.


When does the nuclear membrane and nucleolus reappear?

The nuclear membrane reforms during late telophase of mitosis or meiosis, while the nucleolus reappears during interphase.


Does mass increase during a nuclear change?

No, mass does not increase during a nuclear change. According to the principle of mass-energy equivalence (E=mc^2), the mass of the reactants is converted into energy during a nuclear change.

What is radioactive disintegration series?

A disintegration series is the pathway of a radioactively unstable element into a stable element. The pathway alters the atomic number of the element and converts the element into another element. A common one is the uranium disintegration series.
