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.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
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.
Is an element with eight valence electrons chemically unstable?
An element with eight valence electrons is typically chemically stable, as this configuration corresponds to a full outer shell according to the octet rule. Elements with a full valence shell, such as the noble gases, are generally inert and do not readily participate in chemical reactions. However, under specific conditions or in certain compounds, even these stable elements can exhibit reactivity.
Is sulfur outer most shell stable?
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.
Which noble gases are the most chemically stable?
Gases with eight valence electrons.
What makes atoms have a stable electron configuration?
In order for an atom to be chemically stable it must have 8 valence electrons.
Does two valence electrons is a reactive or non reactive?
Two valence electrons make an atom chemically reactive because it wants to either gain or lose electrons to achieve a full valence shell. This makes it more likely to form bonds with other atoms to reach a stable electron configuration.
How many valence electron are needed for an atom to be stable?
It depends on the atom. List what element the atom is from.
Does xenon have one valence electron with neutral?
No. there are no unpaired electrons in xenon. In neutral form, xenon will have 8 valence electrons.
How many valence electrons will result in chemical stability for an atom?
A full outer shell of electrons typically results in chemical stability for an atom. This corresponds to 8 valence electrons for most atoms (except hydrogen and helium, which only need 2 valence electrons for stability).
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.
