What is the name of the isotope with 86 protons and 136 neutrons?
The isotope with 86 protons and 136 neutrons is radium-222.
How many neutrons are contained in an atom of barium - 136?
The atomic number of barium is 56. So there are 56 protons and 56 electrons.
How many neutrons in a uranium of 230?
Uranium-230 is a radioactive isotope of uranium with 142 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.
What is the ratio of neutrons to protons in a nucleus of radon 222?
The ratio of neutrons to protons in a nucleus of radon-222 can be calculated by subtracting the atomic number from the mass number. For radon-222, the atomic number is 86 and the mass number is 222. Therefore, the ratio of neutrons to protons in radon-222 is 222 - 86 = 136 neutrons to 86 protons.
What element is a radloactive gas with 136 neutrons?
Radon.
What element is a radioactive gas with 136 electrons?
If the gas is neutral this would mean the atom would also contain 136 protons, thus its atom number would be 136. Such an element has never been made (it does not occur naturally) and it would probably be unstable.
What is the name of the isotope with 86 protons and 136 neutrons?
The isotope with 86 protons and 136 neutrons is radium-222.
What happens when two protons and two neutrons are ejected from a radium nucleus?
The radioactive gas radon is obtained: 226Ra-----alpha particle------222Rn
How many neutrons are contained in an atom of barium - 136?
The atomic number of barium is 56. So there are 56 protons and 56 electrons.
Why does thorium undergo radioactive decay?
The ratio neutrons/protons in radioactive isotopes is the cause of their innstability.
How many neutrons in a uranium of 230?
Uranium-230 is a radioactive isotope of uranium with 142 neutrons.

What is the ratio of neutrons to protons in a nucleus of radon 222?
The ratio of neutrons to protons in a nucleus of radon-222 can be calculated by subtracting the atomic number from the mass number. For radon-222, the atomic number is 86 and the mass number is 222. Therefore, the ratio of neutrons to protons in radon-222 is 222 - 86 = 136 neutrons to 86 protons.
How man protons does an element have to have to make it radioactive?
An element can be radioactive regardless of its number of protons. Radioactivity depends on the specific isotopes of an element, which can have different numbers of neutrons. Elements with unstable isotopes that undergo radioactive decay typically have too few or too many neutrons compared to the number of protons.
Is radium a radioactive gas?
Radium is a solid, radon is a gas. Both are radioactive.
What is an atom which has unequal number of protons and neutrons in the nucleus?
Radioactive
