What else can I help you with?
Which noble gases does not have 8 electrons in its highest occupied enegry level?
All noble gasses have 8 valence electrons, it is what makes them "stable" and therefore are non reactive.
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.
Why does helium not have the same number of valence electrons as helium?
Helium is a noble gas and has a full outer electron shell with 2 electrons, making it stable. It does not need to gain or lose electrons to achieve a full outer shell, so it does not have the same number of valence electrons as other elements that need to gain or lose electrons to become stable.
What is the rectivity of the noble gases in terms of valence electrons?
Noble gases are also known as the inert gases, meaning they don't react because they have a stable octet (eight electrons in their valence shell). They all have eight electrons in their valence shell with the exception of helium because helium is rebel, but they are all nonreactive including helium.
How many valence electrons do noble gases have?
Inert gases have 8 valence electrons. This is why they are inert, they have a complete octet formed of electrons and are in their lowest energy configuration.
How many valance 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.
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.
All atoms become stable when they have how many valence electrons?
Atoms become stable when they have a full outer electron shell, which typically means having 8 valence electrons (except for hydrogen and helium, which are stable with 2 valence electrons). This stable configuration is known as the octet rule.
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
What element is stable with 2 valence electrons?
Helium is stable with 2 valence electrons. It has a full outer electron shell, making it chemically inert and stable.
Valence electrons of helium?
Helium has two valence electrons in the 1s orbital.
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
Which noble gases does not have 8 electrons in its highest occupied enegry level?
All noble gasses have 8 valence electrons, it is what makes them "stable" and therefore are non reactive.
How many valence electrons does helium need to have filled outermost energy level?
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
How many valence electrons do stable atoms have?
Oh, dude, stable atoms typically have 8 valence electrons because they want to be all balanced and happy. It's like they're throwing a party and they need 8 cool electrons to join in on the fun. So yeah, 8 valence electrons is the magic number for stable atoms.
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 does a atom become stable?
When the atom has 8 valence electrons.
