SF3- | [:F-S-F:]- || :F: | Yes, it's a reasonable structure.
 | | No, the total number of valence electrons is wrong.
 | | The correct number is: [ ]
 | | No, some atoms have the wrong number of electrons around them.
 | | The symbols of the problem atoms are: [ ]
AlCl3 | :Cl: | Yes, it's a reasonable structure.
 | | :Cl-Al-Cl: | No, the total number of valence electrons is wrong.
 | | The correct number is: [ ]
 | | No, some atoms have the wrong number of electrons around them.
 | | The symbols of the problem atoms are: [ ]
IF4- | [:F F:]- | Yes, it's a reasonable structure.
 | | :I: | No, the total number of valence electrons is wrong.
 | | :F F: | The correct number is: [ ]
