[Ar]3d54s1
Gold is more stable.
Corroded metal is not stable.
Neon is more stable than carbon because it has a full set of electrons in its outer shell, making it incredibly stable and unreactive. Carbon, on the other hand, can form a variety of bonds with other elements, making it more reactive and less stable compared to neon.
The cis-trans isomerism tend to be very stable. Typically, trans isomers are more stable however, an exception lies in cis-trans isomers which makes them more stable than trans isomers.
Chromium (Cr) and Copper (Cu) do not follow the expected electron configuration in the filling of the 4s orbital due to their stability in achieving a half-filled or fully-filled d orbital. By transferring one electron from the 4s orbital to the 3d orbital, both elements achieve a more stable electron configuration, even though it might seem to go against the normal filling order.

[Ar]3d54s1
Perhaps the electronic configuration of Chromium? Ar for argon, argon has 18 electrons. Electronic configuration of argon can be written as 1s22s22p63s23p6. Electronic configuration of chromium is 1s22s22p63s23p63d54s1. As you can see you can just replace that long chain of figures in front of 3d54s1 with just Ar. Hence, [Ar]3d54s1.
More stable
Gold is more stable.
A t least as stable as, say, the USA or Canada, if not more stable. More stable than Iran, Iraq, Pakistan, Afghanistan, Congo. But not as stable as Saudi Arabia, UAE, Oman, Qatar.
no. if the atom is stable it does not need to form any more compounds
Three legs are more stable than 4 legs.
Nitrogen is sufficiently stable.
More stable than the US dollar.
In general, atoms are more stable when they are combined with other atoms to form compounds because this allows them to achieve a full outer electron shell, which is a more stable configuration. Atoms tend to be more reactive when they have incomplete outer shells.
