The atomic number is 86 which gives the number of protons. 220Rn has 220 protons and neutrons so the neutron count iscalcualted as follows:
220 -86 = 134 neutrons
220Rn is an unstable isotope of Radon.

What element will result if two protons and two neutrons are ejected from a uranium nucleus?
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
How many valence electrons does copernicium?
Each isotope of copernicium has a different number of neutrons: 165, 169, 170, 171, 172, 173.
How many valence electrones does Rn have?
Rn or Radon is a noble gas, and has 8 Valence Electrons
What is the electron configuration of curium?
The electron configuration of curium is [Rn]5f7.6d1.7s2.
What is the full form of RN in periodic table?
Full name of Rn?Radon=====
How many protons and how many neutrons has the isotope of radon Rn 210?
The isotope 210Rn has 86 protons and electrons; also 124 neutrons.
How many protons does Rn have?
The number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the isotope - 86 The isotope 222Rn, the most stable (half life = 3,8 days) radon isotope, has 136 neutrons.
How many protons are in element radon?
Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
What is the chemical symbol for thoron?
Thoron is the ld name of the isotope radon-220 (Rn-220).
What is thoron is it an element?
Thoron is a radioactive isotope of radon, Rn 220, having a half-life of 54.5 seconds and produced by the disintegration of thorium
What is the equation for the alpha decay of radium 224?
An alpha particle consists of 2 Neutrons and 2 Protons, therefore A=4, Z=2.For Ra-224: A=224, Z=88.Subtracting the values for the alpha particle from Radium-224:A = (224-4) = 220Z = (88-2) = 86The nucleus with a Z of 86 is Radon, or in this case, Rn-220.So that: Ra-224 --> Rn-220 + AlphaBut alpha particles are just Helium-4 nuclei.Ra-224 --> Rn-220 + He-4
What is the balanced reaction for the predominant method of decay of radon?
In the case of Rn-222, which is the "isotope of concern" because it occurs naturally, it decays as follows: 222Rn => 218Po + He+2 In this equation, we see the radon isotope Rn-222 emit an alpha particle (the helium nucleus) and undergo a transformation to become the polonium isotope, Po-218.
What is the equation to describe the beta decay of polonium -220?
210 4 214 84 PO -------> 2 alpha + 86 RN
What is the charge on plutonium atom?
Nuclear fission of some isotopes release a great quantity of energy. Plutonium is a fissile material (isotopes 239Pu and 241Pu); it is used in nuclear reactors and nuclear weapons. Also Pu(alpha,n)Be is a source of neutrons and Pu is used as power or heat source.
What has the atomic number of 86?
Isotopes are not designated by atomic number. The element with atomic number 88 is Radium. Because different isotopes of the same element vary by the number of neutrons in the nucleus, the isotope is designated by the atomic mass. For example, most carbon atoms have six protons, so the atomic number is 6. The most common isotope has 6 neutrons, so the isotope (Carbon 12) is the same as the atomic mass, 12 (6P + 6N), but there are isotopes with atomic masses of 13 (6P + 7N) and 14 (6P + 8N). Carbon 14 is familar as a dating tool when organic compounds are present. The only isotope given for Radium in the periodic table is 266.
What are berkelium's nuclear properties?
Some berkelium nuclear properties are: - berkelium is radioactive and unstable - berkelium has 26 isotopes and isomers - the electron configuration is [Rn]5f97s2 - berkelium has 97 protons in the nucleus; the number of neutrons is different for each isotope - during disintegration berkelium emit alfa particles, electrons or positrons
What element will result if two protons and two neutrons are ejected from a uranium nucleus?
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
