Only those involved in nuclear reactions. Ordinary chemical reaction can not effect this change.
Protons are positively charged (+) and neutrons don't hold any charge.
The number of protons and neutrons is not changed; sodium lose one electron and chlorine gain an electron.
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
NO,each isotope has different number of neutrons why that? in isotopes the mass number is changed but atomic number(protons) still constant,thus the number of neutrons will be changed
Neutrons are completely separate from protons, so neutrons do not have any protons, and protons do not have any neutrons.

An isotope is a particle that has an unequal number of protons and neutrons. Isotopes of an element have the same number of protons but different numbers of neutrons. These variations in the number of neutrons result in different atomic masses for isotopes of the same element.
Electrons have a negative charge, protons have a positive charge, and neutrons have no charge (they are neutral).
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
None -- all protons are protons, which are different from neutrons.
Protons, neutrons and electronsare the most basic (internal) particles of an atom of any kind. They make the mass (protons and neutrons, both in the nucleus) and chemical properties (elctrons, in particular shells or orbit around the nucleus).
