What isotopes remains after the alpha decay of uranium-238?
232U alpha decays to 228Th. Thorium-228 is the daughter product of the alpha decay of uranium-232.
What is the atomic mass of radon?
The relative atomic mass of radonis indeterminiate because this element is relatively short lived and exists only as a transient decay product.
What are isotopes and how do you label them?
Isotopes are atoms of the same element but with a different number of neutrons.Example for the isotope 228 of uranium:- uranium-228- U-228-- 22892U
How many protons neutrons and electrons are in radium 222?
Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
An atom of thorium loses 2 protons what element would be left?
Radium - 228.
What is the alpha decay of the Thorium isotope Th 232?
Seems some mistake in printing the mass number of thorium. It has to be 227. No Th-225 is available as far as the tables have been analysed. When a alpha particle comes out then the atomic number of parent is reduced by 2 and its mass number will be reduced by 4. So in case of Th-227, it gets changed to Ra-223 after the emission of an alpha particle.

Radon has 86 protons, 86 electrons.Rn-222 isotope has 136 (222 - 86 = 136) neutrons
What is the balanced equation for the alpha decay of radium 228?
224
What is the symbol for an atom of radium 88 protons and 140 neutrons?
Ra-228
An atom of thorium loses 2 protons what element would be left?
Radium - 228.
What has the author J R Noyce written?
J. R. Noyce has written: 'Evaluation of methods for the assay of radium-228 in water' -- subject- s -: Water, Isotopes, Radium, Analysis
Is the number 228 prime?
228 is a composite number and not a prime numberr.
What element does radium become once it has decayed?
Radium undergoes radioactive decay, specifically alpha decay, to become radon. Radium-226 (226Ra) will undergo alpha decay releasing that alpha particle, which is a helium-4 nucleus, to become radon-222 (222Rn).
What is the weight of radium?
Although the atomic mass number of radon is often given as 220, there are 39 isotopes and isomers of radon. The common isomers of radon are : radon-219, radon-220, and radon-222.
