Radon therapy has been used in some spa resorts around the world, but there has never been any proof that there are ...How many protons are in the element at the position Group 2, period 7? Radium. What is the number of protons, neutrons and electrons in Bromine? protons = 35 electrons = 35 neutrons = 44.904 or 45. The atomic number is the same as the. protons. The group number is the same as the. valence electrons. How are elements arranged on the periodic table? 92 protons. All isotopes of uranium, therefore, have 92 protons. However, each uranium isotope has a different number of neutrons: • uranium-238 has 92 protons and 146 neutrons, • uranium-235 has 92 protons and 143 neutrons, and • uranium-234 has 92 protons and 142 neutrons. Some isotopes are stable, or nonradioactive; some are radioactive.

Z = number of orbital electrons; usually = number of protons Each element has a unique atomic number Atomic Mass A = mass of protons + mass of neutrons Within an element, different numbers of neutrons, and hence different values of A (within limits) are possible. The Law of Conservation of Mass applies here: sodium-20 has 11 protons and nine neutrons. If an alpha particle is removed, nine protons and seven neutrons remain; the missing nuclide would be F-16. Keywords Radon, in short, Rn, is a noble gas, that you can't see, smell or taste. In the periodic table, the mass number of radon is 222, meaning that it has 86 protons and 136 neutrons. We call atoms with the same atomic number, but different mass number as "isotopes". There are at least 21 known radon isotopes.

The mass number of the carbon isotope with 8 neutrons is 6 (protons) + 8 (neutrons), or 14. To distinguish one isotope from another, the mass number is given along with the element’s name. Since the mass number is equal to the number of protons plus the number of neutrons, the number of neutrons can easily be determined.
The mass number is a count of the number of particles in an atom's nucleus. Remember that the nucleus is made up of protons and neutrons. So, if we want, we can write: Mass Number = (Number of Protons) + (Number of Neutrons) For krypton, this equation becomes: 84 = (Number of Protons) + (Number of Neutrons)
The universe consists of many elements, all of which are made up of some combination of protons, neutrons and electrons. As you surely remember from chemistry, the number of protons determines the element. For example, carbon atoms have 6 protons in the nucleus.
The atomic number (36) is the number of protons in krypton. Putting this into the equation, we get: 84 = 36 + (Number of Neutrons) What number added to 36 makes 84? Hopefully, you said 48. That is the number of neutrons in an atom of krypton. The interesting thing here is that adding or removing neutrons from an atom does not create a different ...
Valence Electrons. Electrons orbit the nucleus -- made of protons and neutrons -- in concentric levels. The outermost level that contains electrons is called the valence level, and the electrons in this level are called valence electrons. Each group, or column, in the periodic table has a particular number of valence electrons.
The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic mass is 1 because there is one proton and no neutrons. For helium, it is 4: two protons and two neutrons. For most of the 16 lightest elements (up to oxygen) the number of neutrons is equal to the number of protons.
The periodic table lists the atomic mass as 238.039 amu. Round the atomic mass to 238, subtract the atomic number, and you're left with 146 neutrons. Uranium has a large number of neutrons relative to the number of protons, which is why all of its isotopes are radioactive.

Radon is a gas produced by the radioactive decay of the element radium. Radioactive decay is a natural, spontaneous process in which an atom of one element decays or breaks down to form another element by losing atomic particles (protons, neutrons, or electrons). When solid radium decays to form radon gas, it loses two protons and two neutrons.
The number written to the right of the element's name is the mass number. The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope.
The number of protons and neutrons are not always equal so the atomic mass is not always double the number of protons. For example Sodium (Z=11) has 11 protons, 12 Neutrons and 11 electrons so the atomic mass should be 23. In fact it is 22.989. The atomic mass is not normally an exact number but very close.
