What else can I help you with?
What element has a stable 2 valence electrons?
The element with a stable 2 valence electrons is helium. Helium has a full outer electron shell with 2 electrons, making it very stable and unreactive.
What is the most stable atom in the periodic table?
The most stable atom in the periodic table is helium.
Which is more stable He - 4 or He - 6?
Helium-4 (He-4) is more stable than Helium-6 (He-6) because He-4 is a doubly magic isotope with both protons and neutrons arranged in complete shells, leading to higher stability. He-6, on the other hand, has an unstable neutron-proton ratio, making it less stable than He-4.
What is the valency of helium?
Helium has a valency of 0 because it has a full outer shell with 2 electrons, making it stable and unreactive.
How many types of helium there?
"Type" is ambiguous in this context. Do you mean isotopes? Or do you mean states of matter? (Helium has some exotic states of matter.)Wikipedia states that there are 8 helium isotopes, to of them (3-He and 4-He) stable."Type" is ambiguous in this context. Do you mean isotopes?

Is helium stable or unstable?
Helium is a stable element.
What is the half life of helium?
Helium-3 is stable.
Which is the most stable out of the two Oxygen or Helium?
Helium is more stable, because it has completely filled valence orbitals.
How many electrons does it take for hydrogen and helium to become stable?
Helium is already stable. Hydrogen should gain or lose one electron to be stable.
Is helium unstable and also radioactive?
Helium is extremely stable and non radioactive
Can helium turn into air?
Helium cannot turn into anything, it is a stable element.
Why is a helium atom stable with only two electrons in its outermost energy level?
helium has completely filled valence orbitals and hence is stable
Is Helium the first element on the periodic table and the most stable element in the universe?
False (Hydrogen has the first position, Helium is the most stable)
Why is helium non reactant?
Helium has completely filled orbitals, hence it is stable and inert.
Why Helium with equal number of protons and neutrons is stable but Deuterium does not?
On the contrary, deuterium is stable.
Forms 4 strong stable bonds?
Helium, Ne, Ar, Kr, Xe and Rn are stable bonds. Helium has 2 protons and 2 electrons.
How many extra valence electrons does helium need to become stable?
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
