The noble gases - group 18 on most newer periodic tables - are the most stable. They have a completely filled valence shell of electrons.
Having a full valence (outer) shell will make it stable. This means the outer shell will have 8 electrons or in Hydrogen's case, 2 or none.
in the outer most part
They belong to group 18 - noble gases :)
The most stable outer orbital arrangement of electrons after a chemical reaction is 8 electrons. This is referred to as the octet rule in representative elements.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
Since a carbon atom has 4 electrons in its outer shell, it does not have the stable arrangement of 8, which it can gain by sharing electrons with other atoms.
Atoms can achieve a stable outer electron arrangement by gaining, losing or sharing valence electrons with other atoms or ions.
The most stable outer orbital arrangement of electrons after a chemical reaction is 8 electrons. This is referred to as the octet rule in representative elements.
Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.
No. Valence electrons are the electrons in the outer most orbit (or energy level) and not in outer most orbital.
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
Most atoms tend to form the kind of bonds that will give them 8 electrons (an octet) in their outer shell, because that is a particularly stable arrangement. Exceptions are hydrogen and helium. Hydrogen's most stable arrangement is zero electrons (but it can also have 2) and helium has a stable arrangement of 2 electrons. the two lightest metals, lithium and beryllium, also have a stable electron arrangement of just two electrons. All other elements seek 8.

Helium has 2 valence electrons and has completely filled orbitals / shells and helium is stable.
lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell

Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
Carbon and Germanium They all have 4 electrons in their outer orbital
