The electrons are filled in the orbitals according to Hund’s rule. It states that pairing of electrons takes place only after all the degenerate orbitals are half-filled.
If an atom loses electrons, it gets positive charge and if the atom gains electrons, it gets negative charge.
Ground state is the energy state of the molecule when all the electrons are present in lowest possible molecular orbitals.
In excited state, one electron goes from lower energy orbital to higher energy molecular orbital.
A
The atomic number of Fe is 26.
It loses 3 electrons to form ion.
Hence, the number of electrons in is 23.
Therefore, its ground state electron configuration is,

Electron Configurations of lons ③ 19 01 23 Review Constants Periodic Table When an atom forms an ion, it will gain or lose electrons to attain a more stable electron configuration, frequently that of a noblo gas. Nonmetals tend to form anions by gaining electrons, which enter the lowest energy unoccupied orbital. Metais tend to form cations by losing electrons. Main group motals lose electrons in the reverso order of filling. Transition metals, however, lose s electrons first. Part A...
