because the electron tranfer between an atoms and it doesnt belong to one atom
All of the representative elements (s and p block) have predictable electron configurations. However, many of the transition elements have electron configurations that are not predicted by the rules for determining electron configuration.
Chromium and copper are well-known exceptions to the Aufbau principle. Chromium has an electron configuration of [Ar] 3d5 4s1 instead of the expected [Ar] 3d4 4s2, and copper has an electron configuration of [Ar] 3d10 4s1 instead of the expected [Ar] 3d9 4s2.
Paramagnetic substances are those that are weakly attracted to a magnetic field, such as oxygen and aluminum. Diamagnetic substances, on the other hand, are weakly repelled by a magnetic field, like copper and bismuth. The key difference between them lies in their response to magnetic fields: paramagnetic substances are attracted, while diamagnetic substances are repelled.
The electron configuration for copper is Ar 3d10 4s1.
The electron configuration of copper is Ar 3d10 4s1.
Copper and chromium have exceptional configurations due to their half-filled or fully-filled d orbitals, which give them greater stability than expected based on electron configurations alone. This stability arises from the exchange energy associated with the electron-electron repulsions that are minimized in these configurations.

Electron configurations that end with d2 electrons can typically be found in transition metals like chromium (Cr) and copper (Cu). These elements exhibit unique electron configurations due to the stability associated with half-filled or fully filled d orbitals. For example, chromium ends with 3d^5 4s^1 and copper ends with 3d^10 4s^1 configurations.

Two elements that have configurations that are apparent contradictions to the diagonal rule are chromium and copper. These elements have electron configurations of [Ar] 3d5 4s1 and [Ar] 3d10 4s1, respectively, instead of the expected [Ar] 3d4 4s2 and [Ar] 3d9 4s2 configurations based on the Aufbau principle and diagonal rule. This is because having a half-filled d orbital (in the case of chromium) or a fully filled d orbital (in the case of copper) provides greater stability than the predicted configurations.
A paramagnetic element is an element that is weakly attracted to a magnetic field due to the presence of unpaired electrons. Some common examples of paramagnetic elements include oxygen, copper, and aluminum.
