In the nuclear fusion process in the sun, two protons change into a proton and a neutron, plus also a positron and a neutrino. This is part of the synthesis of helium and release of energy which powers the sun. You can see the complete chain of reaction at the link below
They change into neutrons. The reaction is that two protons become one neutron plus one proton, together with one positron and one neutrino. The full sequence in which four protons become one helium nucleus (two protons plus two neutrons) is well illustrated in the link given below., from Wikipedia.
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
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.
A transmutation reaction always involves a change in the identity of the atoms involved, resulting in the formation of different elements. This can be achieved through processes like radioactive decay or nuclear fusion.
In chemical bonding, the number of protons remains the same. That's because the original elements involved in the chemical reaction remain the same as regards their nuclei. Nothing involving the nucleus of an atom is changed in chemical reactions. This differentiates chemical reactions from nuclear reactions, where changes in atomic nuclei are what makes a nuclear reaction a nuclear reaction.
The only way to change the number of protons in an atom is with a nuclear reaction.
the number of protons and neutrons
The subatomic particles that can change in a nuclear reaction are protons, neutrons, and electrons. During nuclear reactions, these particles can be gained or lost, leading to the formation of different elements and isotopes.
Only those involved in nuclear reactions. Ordinary chemical reaction can not effect this change.
They change into neutrons. The reaction is that two protons become one neutron plus one proton, together with one positron and one neutrino.

During a nuclear reaction, the total number of protons and neutrons (mass number) remains constant, as well as the total charge (atomic number) of the atoms involved. The total energy before and after the reaction also remains the same, as dictated by the law of conservation of energy.
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
No, it is a chemical change. ---------------------------------- Yes, it is a physical change because this change not involve a chemical reaction but a nuclear reaction followed by a change in the number of protons and neutrons.
The stability of a nucleus can change during a nuclear reaction by converting one element into another through processes such as fission or fusion. If a nucleus becomes more tightly bound through a reaction, it can increase stability, whereas if it becomes less tightly bound, it can decrease stability. The outcome of the reaction depends on the balance between attractive nuclear forces and repulsive electrostatic forces within the nucleus.
