It depends on which exact version (there are several different versions of the 226). If it is in fair shape, it can be worth $300 to over $1000, depending on the model.
No, they are two very different models in terms of magazine size.
Country code +226 is Burkina Faso, and +226 72 is a Telmob mobile. The remainder of the number will be six more digits.
Radium has an atomic number of 88, meaning it has 88 protons. The most common isotope of radium is radium-226, which has a mass number of 226. This mass number represents the total number of nucleons (protons and neutrons) in the nucleus, so radium-226 has 226 nucleons.
no but 225 is
Yes, it is.
Radium has several isotopes, but the most common one is radium-226. This isotope has an atomic number of 88, indicating it has 88 protons. Since the mass number of radium-226 is 226, it contains a total of 226 nucleons, which includes both protons and neutrons. Therefore, radium-226 has 138 neutrons (226 - 88 = 138).
