Helium has two valence electrons, it has completely filled s orbital and has stable electronic configuration. Hence it is chemically inert

∙ 12y agoHelium is an extremely non-reactive chemical element.
Wiki User
∙ 12y agoit is only unstable when exposed to some other chemicals or if you add way to much it can be lethel like a fart lol but who cares were all gonna die in 2 years
Wiki User
∙ 11y agoHelium is not a fission, it is an element. And fission is a process, specifically, it is the process of something such as an atomic nucleus breaking apart into two or more pieces.

How is hydrogen changed into helium in nuclear fission?
Hydrogen is not changed into helium in nuclear fission. In nuclear physics, nuclear fusion is a reaction in which two or more lighter atomic nuclei are forced together and are fused into a heavier nucleus. In the case of the formation of hydrogen into helium, our sun does that in what is called the proton-proton reaction.
Is uranium on the sun?
no. the sun uses fussion, not fission. fussion requires two hydrogens that "fuse" to make a helium, which gives off a lot more energy then fission. It does not require uranium.
What is the chemical make up elements of the sun?
hydrogen mainly, but there undergo fission to form helium (which undergo fission as the star approaches supernova producing the heavy elements like carbon)
Fast neutron detection by helium 3 ionization chamber?
Helium-3 has a high cross section for thermal neutron absorption. For fast neutrons you must either thermalize the neutrons for use with boron or helium-3 based proportional counters or use a fast fission chamber based on fast fission of uranium. It's worth noting that a uranium based fast fission detector is really only useful in extraordinarily high neutron fluxes like that of a reactor.
Is helium produced only in the cores of stars?
No. Helium nuclei are a common product of nuclear fission, as takes place in nuclear explosions and reactors. These nuclei then pick up electrons from other atoms and become whole helium atoms.
What is the hydrogen to helium reaction that is occurring inside the sun called?
nuclear fission
What are two common fuels used during the process of fission?
hydrogen and helium
Nuclear fission where is it found?
stars.... stars are made of hydrogen, helium, and nuclear fusion

What is associated with a nucleus breaking down and emitting a helium nucleus?
nuclear fission, alpha decay
How does the sun produce all of its energy?
Looking at it very simplistically, the sun contains an enormous amount of hydrogen inside which through the nuclear fission process produces helium. The process of fission (combing of 2 hydrogen atoms into 1 helium atom) releases tremendous amount of energy. The energy is equivalent to the mass that is lost in the fission process.

What is the only naturally occurring element used for nuclear fission?
Plutonium I think.
What process changes hydrogen to helium in a star?
the process is called "nuclear fission ". that means the combining of two hydrogen atoms into one , that is helium . it generates huge amount of energy . it has not yet been done sucessfuly by humans , because it is unstable .however we have controlled nuclear fission . that is just the reverse of it
