Radium has 7 "shells" and has 88 protons and 138 neutrons. it also has 88 electrons.
the electrons are arranged like:
2 (1st shell)
8(2nd)
18(3rd)
32(4th)
18(5th)
8(6th)
2(7th)
Yes, it is true.
There are several isotopes of iron, the most frequent is Fe56 (92 percent). Suggest you look up Wikipedia for Iron. I do not understand your use of word 'resonante'. If you mean 'resonate' I still don't understand what your query really is.
All erbium ordinarily found in nature is of stable isotopes. Like all other elements, erbium has synthetic radioactive isotopes.
Isotopes. They differ in the number of neutrons in the nucleus.
they are known as isotopes. Dont ask people to do your homework
look at a periodic table :)
isotopes is a type of i guess calorie like things you need 4 grams of IT (isotopes) every day
Isotopes have different masses, so the superscript preceding the symbol will be different. An example could be carbon with atomic mass 12 and carbon with atomic mass 14. 12C and 14C with the 12 and 14 being superscripts, identifies the different isotopes.
You don't; you look it up in a table of nuclides. It's very difficult (as in, essentially impossible) to predict things like this.

If you mean oxygen: like most elements, it has both stable isotopes, and unstable (i.e., radioactive) isotopes. 16O, 17O and 18O are stable; the unstable (radioactive) isotopes include 15O and 14O.
The most likely form of fusion to be successful on earth will be to produce helium from hydrogen isotopes. Helium has two protons and two neutrons in its nucleus.

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.
