Verified step by step guidance

Determine the total number of valence electrons for SeF4. Selenium (Se) is in group 16, so it has 6 valence electrons, and each fluorine (F) has 7 valence electrons. Multiply the number of fluorines by 7 and add to selenium's 6.

Draw the Lewis structure of SeF4 by placing selenium in the center and arranging four fluorine atoms around it. Use the valence electrons to form bonds and complete octets, then assign any remaining electrons as lone pairs on selenium.

Count the total number of electron domains around the central selenium atom. Electron domains include bonding pairs (Se-F bonds) and lone pairs on selenium.

Identify the electron domain geometry based on the total number of electron domains using VSEPR theory. For example, 5 electron domains correspond to a trigonal bipyramidal electron domain geometry.

Determine the molecular geometry by considering the positions of the atoms only (ignoring lone pairs). For SeF4, with one lone pair and four bonded atoms, the molecular geometry is seesaw.
