The alpha particle has a composition identical to a helium nucleus, specifically, the nucleus of helium-4. The alpha particle, however, is a product of radioactive decay, and is usually moving pretty fast. When we speak of helium nuclei, we are usually speaking of things that are much less energetic.
What else can I help you with?
What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.
Is helium gas a pure substance or mixture?
Helium is pure as it is on the periodic table.
What is the resulting nucleus if a tritium and a deuterium nucleus fuse?
Helium and a neutron: D + T --> He + n + 17.59 MeV
Is helium a pure substance or a homogeneous or heterogeneous mixture?
Helium is an element which makes it a pure substance.
What is one type of substance which contains only one atom?
One type of substance that contains only one type of atom is an element. For example, helium (He) is a noble gas that consists solely of helium atoms. Elements are the simplest forms of matter and cannot be broken down into simpler substances by chemical means. Each element is defined by its unique number of protons in the atomic nucleus.
Type of nuclear decay consisting of a helium nucleus?
Alpha decay. Alpha particles are the same as a helium-4 nucleus.
What type nuclear decay produces particles that are identical to the helium nucleus?
an alpha particle
What type of nucleus is during a solar nuclear reaction by the fusion of four nuclei?
During a solar nuclear reaction, the type of nucleus formed by the fusion of four nuclei is a helium nucleus, also known as an alpha particle. This process is known as nuclear fusion and is responsible for the energy production in the core of the Sun.
This type of nucleus is formed during a solar nuclear reaction by the fusion of four nuclei.?
A helium nucleus, also known as an alpha particle, is formed during a solar nuclear reaction by the fusion of four hydrogen nuclei.
What type of nuclear reaction results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus?
The nuclear reaction that results in a single nucleus undergoing a decrease in atomic number and the release of a helium nucleus is called alpha decay. In this process, an unstable nucleus emits an alpha particle (helium nucleus) which consists of two protons and two neutrons, causing the original nucleus to decrease in atomic number by 2.

What is the resulting nucleus if a tritium and a deuterium nucleus fuse?
Helium and a neutron: D + T --> He + n + 17.59 MeV
Is the helium in a balloon a substance or a mixture?
Helium is an element (and therefore a pure substance) yes
What type of nucleus forms during a solar nuclear reaction by the fusion of four nuclei?
The helium nucleus is formed during the proton-proton reaction by the fusion of four protons. Two of the protons are converted to neutrons by the weak interaction.
What type of radioactive decay removes a helium nucleus and has a very low enegry level?
A helium nucleus - more precisely, a helium-4 nucleus - is called an alpha particle. The corresponding decay would be called alpha decay.
Is helium a pure substance or a homogeneous or heterogeneous mixture?
Helium is an element which makes it a pure substance.
What is one type of substance which contains only one atom?
One type of substance that contains only one type of atom is an element. For example, helium (He) is a noble gas that consists solely of helium atoms. Elements are the simplest forms of matter and cannot be broken down into simpler substances by chemical means. Each element is defined by its unique number of protons in the atomic nucleus.
