- Find Radon (Atomic Symbol Rn) on the periodic table. The smaller number is the atomic number, representing the number of protons. Radon has an atomic number of 86 and therefore 86 protons. Ignore the atomic mass off the periodic table since this is the atomic mass of the average Radon found in nature.
- 2 days ago · An atom has 40 electrons and 51 neutrons. What is its mass number, and how many protons does it have? What does the top number in isotope notation represent? What does the bottom number in isotope notation represent? What is the isotope notation for an atom of carbon-12? What is the isotope notation for an atom of chlorine-37?
- Jan 01, 2011 · 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.

- Atoms are made up of protons and neutrons, collectively called nucleons, surrounded by electrons. Things you need to know: The atomic number of an element (Z) is the number of protons in a nucleus. This determines what the element is. The mass number of an element (A) is the number of nucleons in a nucleus. The number of neutrons in a nucleus ...

atom has 36 protons. The number following the element name in krypton-81 is this nuclide’s mass number. The difference between the mass number (the sum of the numbers of protons and neutrons) and the atomic number (the number of protons) is equal to the number of neutrons, so krypton-81 has 45 neutrons (81 - 36). For example, they may have a high number of neutrons; in other words, they are too big. Such nuclei tend to change their structure by, e. g., getting smaller by alpha particle emission (two protons and two neurons in a helium nucleus), or they change a neutron to a proton, while emitting an electron (beta minus decay). (1) 27 protons and 31 neutrons (3) 59 protons and 60 neutrons (2) 27 protons and 32 neutrons (4) 60 protons and 60 neutrons _____ 25. The stability of an isotope is based on its (1) number of neutrons, only (3) ratio of neutrons to protons (2) number of protons, only (4) ratio of electrons to protons This isotope of carbon has 6 protons and 6 neutrons. Thus, each proton and neutron has a mass of about 1 amu. Isotope: Atoms of the same element with the same atomic number, but different number of neutrons. Isotope of an element is defined by the sum of the number of protons and neutrons in its nucleus. Rn (Radon) atomic number 86, mass number 222, #protons 86, #electrons 86, #neutrons 136 How many protons, neutrons, and electrons does one atom of the following elements have? Mn, W, Rn Since neutrons have no electrical charge, changing the number of neutrons does not affect the chemistry of the element. It does, however, change the mass of the element. Isotopes are identified by their mass, which is the total number of protons and neutrons. There are two ways that isotopes are generally written. A)neutrons, but a different number of protons B)protons, but a different number of neutrons C)protons, but a different number of electrons D)electrons, but a different number of protons 4.Atoms of 16O, 17O, and 18O have the same number of A)a ground-state electron B)a stable nucleus C)an excited electron D)an unstable nucleus
