What is the number of valency electron in helium?
Helium has two valence electrons.
Does H and HE have the same valence electron configuration?
Hydrogen and helium have different valence electron configurations. Hydrogen has one valence electron, and helium has two valence electrons. However, hydrogen does typically form covalent bonds in which it shares an electron, and thereby gains an effective electron configuration of two, like helium. Hydrogen also can form the H+ ion which has no electrons.
What is the Valence electron in He?
helium has only one shell with two electrons and can be considered to be as the valence electrons.
How many electron are in the outer shell of helium?
2 valence electrons for helium (helium has only 1 shell)
What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
What is special about the outer electron orbits of helium?
Helium has only two valence electrons. All other noble gases have 8 valence electrons.
Why does helium belongs to noble gases where infact it has 2 valence electron?
Because helium has completely filled valence orbitals similar to other noble gases.
What doesn't helium react with?
Because the valence electron shell is already filled.
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.
How many electrons are in the outer energy level of a helium atom?
Helium and hydrogen and group 3 to 12 got 2 valence electron
What is the number of valence electron for the elements in Group 8A?
Eight, except for helium which has two.
How many valence electrons do atoms in period 1 have?
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
