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

Is a change that produces a new element a physical change?
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.
In the nuclear reaction that takes place in the sun two protons change into two what?
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.
What happens to the number of protons during chemical bonding?
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.
What does a transmutation reaction always have to involve?
Transmutation always involves a change in the number of protons in the atom, which changes the atomic number and the element of the atom. It also involves at least some slight change in the mass of the atom (but not necessarily the mass number, which is the number of protons plus the number of neutrons, and not the same as the actual mass).
What produces the large amount of energy released by the nuclear reaction?
A change from one form of matter to another, with the release of large amounts of energy.
What is it called when the number of protons in an atom change?
The only way to change the number of protons in an atom is with a nuclear reaction.
What parts of an atom can change during a nuclear reaction that can't change in a chemical reaction?
the number of protons and neutrons

What kind of neutrons are changed into protons?
Only those involved in nuclear reactions. Ordinary chemical reaction can not effect this change.

What is nuclear change reaction?
its a changw
Nuclear reactions change the composition of an atom's?
Nuclear reactions change the composition of an atom's nucleus, hence nuclear reaction.
Which particles that make up an atom are involved in nuclear reactions?
Protons, electrons, and neutrons are the subatomic particles that are involved in nuclear reactions.
Which of the following statements is true Chemical reaction rates vary with the conditions of the change but nuclear rates do not Nuclear decay rates vary with the condition?
"Chemical reaction rates vary with the conditions of the change but nuclear rates do not."
What atomic particle must undergo a change in number during every transmutation reaction?
Nuclear transmutation happens in most (not all) types of nuclear decay. In transmutation, the number of neutrons might remain the same, but the number of protons certainly does not, because the number of protons determines the atomic number of the atom, and transmutation requires a change in atomic number. Since the number of electrons of an unionized atom is the same as the number of protons, the number of electrons would probably change too, but this is not technically a requirement of transformation.I want to point out also that the individual particles usually do not change in transformation (though this can happen), just their number.
What type of reaction results in the change of protons and neutrons?
radioactive decay
Does temperature change during a nuclear reaction?
Yes. Very much. That is how we get useful heat to make steam, to turn turbines, to make electricity.
