Homework Answers
In first question option 4 is the answer. As the rule is 1s2s2p3s3p4s3d4p for filling the electrons which is not followed there.
In second question option 4 is correct as the 11 electrons for sodium are well filled in the shells.
Hope this helps you?.

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...
