Uranium-235 decays naturally, by alpha decay. write the balance decay equation below

If all you are getting is Th then the balanced equation is written below

The Uranium 235 decays into Thorium 231 and an alpha particle.

I'm not sure this decay happens in nature, but Uranium 238 does decay this way.

6/12=1/2

step-by-step explanation:

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
