How do you draw the lewis structure for bromine trifluoride? I know it has 28 valence electrons, but when I draw the lewis structure I can't figure out how to draw the bonds in a way to complete the octet.

Br would be in the center will 3 single bonds to Flourines. Draw in 3 lone pairs for each flourine to complete the octet for them, and add 2 lone pairs onto the Br in the center. In this case, Br is capable is having more than an octet.

Br shares electrons with 3 F and has two lone pairs of its own because it exceeds the octet rule
