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.
What else can I help you with?
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 term for the element that a radioactive isotope decays into is called the "daughter product". During radioactive decay, the original isotope transforms into a different element or isotope through a series of decay reactions.
What is another name for beta particle?
Another name for a beta particle is an electron. It is a high-energy, high-speed particle that is emitted during the radioactive decay of certain elements.
What is The spontaneous decay of an atom is called?
Nuclear decay.Different types of nuclear decay include:Alpha Decay, where the nucleus ejects a charged particle made of protons and neutrons.Beta Decay, where a neutron turns into a proton, a Beta particle (an electron or positron) and a neutrino.Gamma radiation can also be emitted in these processes.
What is the release of a helium atom involved in?
This is the alpha radioactive decay.
Does alpha decay produce helium atoms?
No, alpha decay does not directly produce helium atoms. Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons. This alpha particle is the same as a helium-4 nucleus, but it is not considered a helium atom until it captures electrons and becomes electrically neutral.
What radioactive atoms spontaneously do?
Radioactive atoms spontaneously decay, emitting particles or energy in the process. This decay can result in the transformation of the atom into a different element or isotope to achieve a more stable state.
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.
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.
Is the atom left after decay often radioactive?
Yes, the atom left after decay is often radioactive because the decay process can lead to the creation of unstable isotopes that emit radiation. This radiation can continue to decay until a stable atom is formed.
Bombarding a lithium-6 atom with a neutron produces helium-4 and another particle.what is that particle?

What is when the nucleus of an atom decomposes called?
radioactive decay
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.
What part of an atom causes radioactivity?
It is the nucleus of the atom that undergoes change during radioactive decay.
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 process is a radioactive decay?
The process of a radioactive decay is atomic nucleus of an unstable atom loses energy by emitting ionizing particles
