Analyzing the structures of each given molecules:

a. For XeF3+, Xe will appear as the central atom (less electronegative than F) where F atoms are single bonded to it

  • Valence electrons of Xe is 8 while F is 7. Total valence electron is 28. 8(1) + 7(3) - 1 (positive charge) = 28
  • Each F atoms will appear to have 3 lone pairs while Xe will appear to have 2 lone pairs (7 electrons around Xe) and 3 electrons used for bonding
  • Structure will appear as:

  • Geometry formula appears to be AX3E2 where A is central atom, X are surrounding atoms and E are # of lone pairs.
