What do a beryllium ion and neon atom have in common?
The beryllium ion Be2+ has the electronic configuration 1s2, a full valence shell, the same as helium, an inert gas. Neon is an inert gas, with an electronic configuration of 1s2 2s2 2p6.Be2+ and Ne therefore both have inert gas configurations and have full valence shells.
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.
How many more valance electrons does oxygen need to have a full outer valence shell?
None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.
Will helium catch fire?
No. Helium is a completley inert gas and is not known to undergo ANY chemical reactions.
What element has 8 electrons in 1 atom?
These are the Noble gases which are generally inert. (Except for Helium, which has two electrons, but which is still considered a Noble Gas.)
Helium is what type of element?
Helium is a noble gas with 2 valence electrons.
Is krypton oxidation?
Krypton is an inert gas.
What is inert gas configuration?
having 8 electron in the outermost shell or in valence shell....
What makes neon an inert gas?
Noble gases (such as neon) have full valence electron shells (8 electrons).
What element is nonreactive but only has 2 valence electrons?
Helium, it is the most inert gas (element ) of all.
Why is helium placed in group 8 if it has two valence electrons?
Since 2 electrons fills it's outer shell it is considered an inert gas.
What is the atom called if the outer shell is full of electrons?
A full outer electron shell, the so-called valence shell, creates an inert gas in those elements (the inert or noble gases). In other elements, what is called "inert gas configuration" will apear in the Halogens (the Group 17 elements) and some Group 16 elements. When they "borrow" an electron or electrons in an ionic bond, they do so to achieve "inert gas configuration" by "filling" their valence shell with the borrowed electrons.
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.
What happens to the reactivity of any atom or ion that acquires the same electronic structure as an inert gas?
any atom that has or acquires a valence shell containing exactly eight electrons often is or becomes quite inert.
Why do the inert gas atoms almost never participate in ionic or covalent bonds?
because they already have 8 valence electrons (or 2 in heliums case) in their outer shell. They don't need anymore electrons
Is helium inert gas?
Yes, because it has a complete valence orbit.
How many valence electrons does He have?
Helium has 8 valence electrons. It is a noble gas. none = 0
