Helium has two naturally occurring isotopes, 3He and 4He. Both are stable, so helium does not undergo decay in nature. Several synthetic isotopes exist.
5He is highly unstable and decays to 4He by emitting a neutron.
6He undergoes negative beta decay, producing 6Li. It has the longest half-life of any radioactive helium isotope, at 0.808 seconds.
7He is highly unstable and decays to 6He by emitting a neutron.
8He undergoes negative beta decay, followed immediately by emitting of a neutron, producing 7Li. Its half-life is 0.122 seconds.
9He is highly unstable and decays to 8He by emitting a neutron.
10He is highly unstable and decays to 9He by emitting a neutron.

Bombarding a lithium-6 atom with a neutron produces helium-4 and another particle.what is that particle?
if you bombard a lithium 6 atom with a neutron, then it will form a helium 4 or alpha decay particle and a hydrogen 3 atom, but i dont see that happening, i would think you would need a bigger atom for it to go through radioactive decay, but im just giving my opinion, it could happen just as surely as i think it doesnt. but if alpha decay was to happen to a lithium 6 atom from neutron bombardment, you would get a helium 4 atom and a hydrogen 3 atom.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
What is the term for the element that a radioactive isotope decay into?
The atom that results from nuclear decay is called the daughter atom. The element of the daughter atom would be called the daughter element. The atom that decayed is called the parent.
Why do some isotopes of elements spontaneously undergo radioactive decay?
Nuclei undergo radioactive decay in order to release some of the "stress" in the atom. At a certain point, the nucleus of an atom gets too large to sustain all of those protons and neutrons. When the "stress" is relieved, a phenomenon called radioactive decay occurs.
What kind of decay results in the formation of a different element?
both top and bottomAlpha decay is a kind of radioactive decay in which an alpha particle is emitted from an atom. An alpha particle consists of two protons and two neutrons. Therefore, when an atom of an element undergoes alpha decay, it loses two protons, which changes the atom from one element to another. This is because each different element is identified by the number of protons in its nuclei.or to be more blunt without all the detail radioactive
What is the release of a helium atom involved in?
This is the alpha radioactive decay.
Does alpha decay produce helium atoms?
Yes, alpha decay does produce helium atoms. Alpha decay occurs when a radioactive nucleus emits an alpha particle, which consists of two protons and two neutrons. This combination of particles is the same as a helium atom nucleus, so the resulting particle is a helium atom.

What radioactive atoms spontaneously do?
Depending on the type of atom, a radioactive atom will decay by emitting an alpha particle (helium nucleus), proton, neutron, electron, or will split apart completely.
What has two protons and two neutrons and is identical to a helium nucleus?
An alpha particle, one of the possible emissions in radioactive decay.
What is the final result of radioactive decay?
radioactive isotope
Is an alpha particle radioactive?
An alpha particle itself is not radioactive, but it is the result of a type of radioactive decay called (obviously) alpha decay. The alpha particle is actually a helium-4 nucleus, and it will eventually pick up a pair of electrons and become an atom of that inert or noble gas.
What is an atom stable?
An atom is stable if it does not undergo decay.
What is when the nucleus of an atom decomposes called?
radioactive decay
Is the atom left after decay often radioactive?
Truw
When radioactive decay occurs a atom is always produced by the action?
During any type of radioactive decay, one isotope (type of atom) will convert into a different isotope.
When an atom undergoes radioactive decay the energy released in the reaction comes from what?
The energy that comes from the radioactive decay of an atom can come from the electrons and can come from the strong force inside the nucleus.
