Does noble gases have full valence shells?
Their shells are always full (unless something wacky happens). This is why they are so unreactive.
Why is group 18 most stable on the periodic table?
An atom is stable, and unreactive, if it has a full outer shell.That is, if it has 2, 10, 18 or 20 electrons.Atoms with any other number of electrons do not have full outer shells, and thus are unstable and reactive.
What is the least reactive groups on the periodic table?
Noble gases are least reactive because they have a full shell
Is neon highly reactive?
No, not really. Neon is a Noble Gas meaning it has all the shells in its atom filled so it doesn't really share, gain, or lose electrons. Study has shown it could possibly combine with Fluorine.
What is the least reactive substance known to man?
I believe it to be Argon The noble gases are all unreactive because their outer shells are all full. These include argon, krypton, radon, neon, helium and xenon.
What are the least reactive nonmetals that ave full valence shells?
The Nobel gasses. Generally inert.
Why is the noble gases the most stable?
Their valence shells are completely full, so they are least likely to be reactive and are thus most stable.
Do noble gases readily share their valence electrons?
I don't think noble gasses have valence electrons. They are noble because all their shells are full which makes them not as reactive.
Does noble gases have full valence shells?
Their shells are always full (unless something wacky happens). This is why they are so unreactive.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
What atoms have a full set of electrons in the outer level?
Noble gases, or elements of the 18th group have full valence shells. In other words helium, neon, argon, krypton, xenon, radon and ununoctium have full valence shells.
Is noble gases the least reactive elements on the periodic table?
Noble gases have completely filled orbitals. They generally have 8 valence electrons (helium has only 2) and obey octet rule (stable electronic configuration). Hence they are chemically inert (or do not react with other elements).
What is the group that are made up of nonreactive compounds and all their valence shells are full?
The noble gases, group 18 or group zero. The valence shells are full for He and Ne. the reat have ns2np6 configurations which are obviously not full but provide great stability.
Valence electrons determine an atoms what?
They tell you how reactive the element is. If the atom has only one electron, then it is highly reactive. If the valence shell is full, then it will not react with other elements.
Why is group 18 most stable on the periodic table?
An atom is stable, and unreactive, if it has a full outer shell.That is, if it has 2, 10, 18 or 20 electrons.Atoms with any other number of electrons do not have full outer shells, and thus are unstable and reactive.
Why do atoms of different elements bond together?
They like to have full valence shells.
Why are alkali metals more reactive than alkaline earth metal?
All atoms want to do is make their valence shell full. In alkali metals they have all of their shells completely full except one valence electron. The alkali metals REALLY want to get rid of that electron, so they will react with many elements/compounds to get rid of that electron. In alkaline earth metals they have all of their shells completely full except for two valence electrons. They also want to get rid of those electrons but the alkaline earth metals are not as desperate to do so as the alkali earth metals which make the alkaline much less reactive than the alkali metals.
