What else can I help you with?
Is the helium nucleus a byproduct of fission?
Yes, but only if the nuclear disintegration is alpha decay. Alpha decay is only one mode of radioactive decay, and in alpha decay, a helium-4 nucleus (the alpha particle) will appear. Beta decay (two types) and spontaneous fission are also modes of radioactive decay, and different particles appear in those events. Links are provided below to Related questions that will help you sort this out.
What type of radiation is emitted by thorium?
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
Alpha and beta decay emit what?
Alpha decay emits an alpha particle, which consists of two protons and two neutrons. Beta decay emits either an electron (beta minus decay) or a positron (beta plus decay).
Non-example of alpha decay?
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.
What type of nuclear decay does Uranium undergo?
Uranium has a different decay chain/series for its different isotopes. Uranium 238 for example first decays to thorium 234 through alpha decay while U235 alpha decays to thorium 231. Both have different half lifes which can be found on a natural decay series chart for the said element. The thorium in either case then beta decays to another element.

What is the nuclear decay equation for uranium-238 to strontium-90?
The equation for the beta decay of 87Kr is: 3687Kr --> 3787Rb + -10e where -10e represents a negative beta particle or electron.
What are two different forms of radioactive decay?
Alpha and beta decays.
Order gamma decay beta decay and alpha deacy form weakest to strongest?
From weakest to strongest decay, the order is: Gamma decay - involves the emission of high-energy photons. Beta decay - involves the emission of beta particles (electrons or positrons). Alpha decay - involves the emission of alpha particles (helium nuclei).
Non-example of alpha decay?
Beta decay is a non-example of alpha decay. Beta decay involves the emission of a beta particle (either an electron or a positron) from an unstable atomic nucleus, whereas alpha decay involves the emission of an alpha particle (helium nucleus) from a nucleus.
In alpha and beta decay the parent elements is always a different element from the daughter element?
true
What do unstable isotopes become when they decay?
Unstable isotopes become more stable isotopes or different elements when they decay through processes such as alpha or beta decay. The decay results in the emission of radiation in the form of alpha or beta particles and gamma rays.
What atom is left when a nucleus disintegrates?
There are a number of possibilities as regards what happens when a nucleus "disintegrates" as was asked. There are a number of way that a nucleus can disintegrate, or change, so let's look at those. First there is spontaneous fission. You're familiar with fission because that's what happens in nuclear reactors, to name one thing. But in spontaneous fission, no neutron capture precedes the fission event. The atomic nucleus just "splits" on its own. Uranium, plutonium and a few other elements can do this, and there are a number of different possibilities as regards what fission fragments will result. Some unstable nuclei undergo what is called alpha decay. The nucleus dumps an alpha particle, which is actually a helium-4 nucleus, and is composed of a pair of protons and a pair of neutrons. There are a number of different alpha emitters known, and radon-222 is an example. It turns out that this isotope of radon appears when radium-226 undergoes alpha decay. In the event beta decay occurs, nuclear changes follow. There are two different types of beta decay, and they are beta plus decay and beta minus decay. An example is caesium-137, which will undergo a beta minus decay. It is sodium-22 that undergoes beta plus decay. As you can see, there are several different "disintegration modes" possible in nuclear decay. And there are basket full of possibilities when we look through them, so we can't list them all here. But we can give you links to each of these decay modes, and you'll find them below.
When an atom undergoes radioactive decay does it become a different element?
That depends on the type of decay, alpha and beta decay change the atom into a different element but gamma decay does not.
What type of nuclear decay does Uranium undergo?
Uranium has a different decay chain/series for its different isotopes. Uranium 238 for example first decays to thorium 234 through alpha decay while U235 alpha decays to thorium 231. Both have different half lifes which can be found on a natural decay series chart for the said element. The thorium in either case then beta decays to another element.
