They have different number of neutrons
Isotopes have same number of electrons, same atomic no. but different mass no. They are from the same element like isotopes of carbon. They are not having same number of neutrons. They show same electronic configuration.
All of the atoms of a particular element have the same number of protons. But the number of neutrons can differ by a few. Atoms with different numbers of neutrons are the different "isotopes" of the element. All the atoms behave the same way in chemical reactions, because they are the same element. In order to separate out the various isotopes, you have to use something like a centrifuge to sort them out by mass.
Sodium is a metal atomic element. So it has no molecules (or whatsoever) in it. It is build up (like all elements) with a nucleus in the center and electrons 'rotating' in shells around it. The numbers and measures of those shells and the electrons therein differ from element to element. There are about 100 elements.
That sounds like hydrogen!
Differences in IsotopesThey have different numbers of neutrons and therefore different mass numbers.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.

No, coinium is not a good analogy or model for isotopes. Isotopes are atoms of the same element with different numbers of neutrons, while coinium is a hypothetical element used to illustrate the concept of isotopes in a simplified manner. It is important to understand that isotopes are real atomic entities with distinct properties, not just placeholders like coinium.
Sodium is a very reactive chemical element.
The atomic number of the isotopes of an chemical element is the same; only the atomic mass of the isotopes is different. Also the isotopes of an element have the same chemical and physical properties (of course with some approximation).
Yes: Naturally occurring silicon contains isotopes with mass numbers 28, 29, and 30 in order of decreasing abundance. As with almost any element, many artificial, radioactive isotopes are also known.
Most elements - metals and non-metals - have both stable and radioactivie isotopes. If an element is a type of atom, an isotope is something like a "sub-type". Two isotopes of the same element have the same number of protons, but a different number of neutrons.Most elements - metals and non-metals - have both stable and radioactivie isotopes.
