• 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.

Neutrons do not ionize atoms in the same way that charged particles such as protons and electrons do (by the excitation of an electron), because neutrons have no charge. It is through their absorption by nuclei which then become unstable that they cause ionization. Hence, neutrons are said to be "indirectly ionizing."

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.

Isotopes have the same number of protons, but different numbers of neutrons. This means that while the atomic number of an element will NEVER change… The MASS of the atom can change quite a bit depending how many neutrons there are The number of protons in an atom is also called the “atomic number”.
Apr 03, 2019 · From the periodic table, by reading the atomic number, you can determine the number of protons and electrons in a neutral atom of an element. The number of neutrons can also be determined if the mass number of the atom is known. UNDERSTANDING PERIODS AND GROUPS. Elements of the periodic table are arranged in periods and in groups.
Neutrons do not ionize atoms in the same way that charged particles such as protons and electrons do (by the excitation of an electron), because neutrons have no charge. It is through their absorption by nuclei which then become unstable that they cause ionization. Hence, neutrons are said to be "indirectly ionizing."

There are many natural sources of radiation. Many common elements have naturally occurring radioactive isotopes ( an isotope is an element with the same number of protons, but different numbers of neutrons; e.g. carbon-12 [6 protons and 6 neutrons] and carbon-14 [6 protons and 8 neutrons]). Some of the most common sources of natural radiation are:
    The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.
