What is a noble gas but does not have 8 valence electrons?
Helium is the only noble gas that doesn't have 8 valence electrons. It only has 2.
Which noble gas doesn't have 8 outer electrons?
Helium has only 2 valence electrons. The rest noble gases have eight.
All noble gases have 8 valence electrons except for?
Helium is the noble gas with only 2 valence electrons
What noble gas doesn't have 8 valence electrons it only has what?
He does not have 8 valence electrons. It has only 2 valency electrons.
How valence electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
Do all noble gases have eight valence electrons?
Yes, except for helium which only two electrons. All noble gases are found under the noble gas family to the far right of the periodic table.
How many valence electrons each noble gas has?
Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2 valence electrons) and have stable electronic configuration.
How many valence electrons do argon has?
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
How many valence does argon has?
Argon is a noble gas. It has a full valence shell and thus, 8 electrons.
What is unusual about helium?
Helium is a noble gas with 2 valence electrons. All other noble gases have 8 valence electrons.
How many valence electrons does He have?
Helium has 8 valence electrons. It is a noble gas. none = 0
What are valence electrons and how do they relate to the noble gases?
Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.
