a chlorine atom.
Chlorine becomes negatively charged.
Sodium and chlorine are elements. If you mean one sodium atom and one chlorine atom yes they would be both isotopes but of different elemnts. If they were randomly sampled from nature the sodium atom would almost certainly be sodium-23 (there is only a trace of sodium-22 found in nature) and the chlorine atom would most likely be chlorine-35 as this isotope is about 75% of chlorine)
Yes, Chlorine atom is stable
It becomes an ion with a larger radius than the atom of chlorine
No. The nucleus of an atom contains protons and neutrons, but not electrons. Electrons are found in orbitals surrounding the nucleus.
