The most stable number of valence electrons is 2 for hydrogen and helium, which have only one electron shell in the shell model for atomic electron configurations, and 8 for all other elements.
Most elements need 8 electrons in their valence shells.
They r noble gases which have stable valance shell and grotp no. 18
Valence Electrons are the electrons that are located furthest away from the atom itself in the outermost electron shell. They are located on the last energy level also known as the valence level.
An element's most likely oxidation state is often related to its number of valence electrons. The oxidation state is typically the charge an atom assumes when it forms ions, and it tends to be the same as the number of valence electrons the atom gains or loses to achieve a stable electron configuration.
The number of covalent bonds an atom forms is determined by its valence electrons, specifically the number of electrons needed to achieve a full valence shell (typically 8 electrons for most atoms). Atoms will bond with other atoms to share electrons and reach a more stable electron configuration.
No, sulfur has only 6 valence electrons. Atoms with 8 valence electrons are most stable and generally chemically inert.

less stable
Gases with eight valence electrons.
The most valence electrons an atom can contain is eight.
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.
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.
The electrons in the outermost energy level of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to achieve a stable configuration.
Most atoms need eight valence electrons to have a complete outer shell and achieve a stable, "happy" state, a concept known as the octet rule. However, there are exceptions, such as hydrogen and helium, which are stable with just two valence electrons. Atoms tend to gain, lose, or share electrons to reach this stable configuration.
