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.
A full valence shell of electrons means that the atom is unstable and likely to combine with other atoms?
Actually, a full valence shell of electrons makes an atom stable, as it follows the octet rule. Atoms with full valence shells are less likely to react with other atoms because they are already in a stable configuration.
Is each ion stable?
No, not all ions are stable. Ions can be stable or unstable depending on their electron configuration. Stable ions often have a full valence shell, while unstable ions may have an incomplete valence shell, leading to reactivity in order to achieve stability through gaining or losing electrons.
How are valence electrons related to stability?
Valence electrons are the outermost electrons in an atom, and they determine the atom's chemical properties. Atoms with a full valence shell of electrons tend to be stable because they have a lower energy state. Atoms will gain, lose, or share electrons to achieve a full valence shell, which increases their stability.
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.
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.
What are the conditions for stable electric configuration?
The valence/outer shell has to be completely full to be completely stable.

If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
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.
Valence electrons found where?
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.
What is the outer shell of the noble gases called?
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.
Is each ion stable?
No, not all ions are stable. Ions can be stable or unstable depending on their electron configuration. Stable ions often have a full valence shell, while unstable ions may have an incomplete valence shell, leading to reactivity in order to achieve stability through gaining or losing 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.
Do ions have a full valence shell?
No, atoms with filled valence shells do not tend to form chemical bonds because a filled valence shell means the atom is already stable. It doesn't "want" to share with or take electrons from other atoms to become stable. Although sometimes, these atoms can be found in compounds, it takes a great deal of energy and forcing.
