yes that is true, it does make up an atom stable.
The actual configuration is [Ar] 4s^1 3d^10. Copper is anomalous. The atom is more stable with a full 3d shell and a partially filled 4s shell than it would be if it had a full 4s shell and a partially filled 3d shell.
A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.
An atom with an incompletely filled outermost energy level is likely to be reactive. This is because atoms tend to gain, lose, or share electrons to achieve a stable outer electron configuration. Atoms with incomplete outermost energy levels are looking to fill or empty their outermost energy level to achieve stability.
Lithium bonds due to its tendency to lose an electron and achieve a stable electron configuration. By losing this electron, lithium can attain a full outer energy level, making it more stable and forming bonds with other elements to satisfy its electron needs.
According to the octet rule, sodium will lose its one electron to achieve a full outer energy level, making it stable. This forms a positively charged sodium ion with a stable electron configuration.
A completley filled out electron level makes the atom stable
No, an electron cannot jump to a filled energy level because Pauli's exclusion principle states that no two electrons can occupy the same quantum state simultaneously. Electrons can only transition to higher energy levels that are unoccupied or partially filled, allowing them to move to states that are energetically favorable. When an energy level is filled, it lacks available states for an electron to occupy.
Because their outermost energy level is only partially filled, some elements are highly reactive, I believe.
A half filled sub-shell is more stable than other partially filled shells. As an example use Chromium. It should by logic have the following: Sc = [Ar]4s23d1 Ti = [Ar]4s23d2 V = [Ar]4s23d3 Cr should in theory be Cr = [Ar]4s23d4 but it is not. Half filled shells are more stable so the configuration is Cr = [Ar]4s13d5 two half filled sub levels and then Manganese is Mn = [Ar]4s23d5 one full and one half filled level.
An atom will give up an electron when it is more stable by achieving a full outer electron shell. This typically occurs when the atom is in an ionic bond or is trying to achieve a more stable electron configuration.

If the outer energy level of an atom is already filled with electrons, it is less likely to react because atoms tend to be more stable when their outer energy levels are full. This full outer level signifies that the atom has achieved a more stable electron configuration (usually the octet rule for most elements).
A duplet electron configuration is considered stable, as it corresponds to having two electrons in the outer energy level, which is the most stable configuration for elements in the first period. Elements like helium achieve a duplet electron configuration and are relatively stable due to their full outermost energy level.
Stable.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
