Drawing the Lewis Structure for BrO-

Viewing Notes:

  • The BrO- Lewis structure has a total of 14 valence electrons. This includes the electron represented by the negative charge in BrO-.
  • You need to put brackets around the BrO- Lewis structure as well as a negative charge to show that the structure is a negative ion.


Transcript: This is the BrO- Lewis structure. Bromine, we have 7 valence electrons. Oxygen has 6. We add this in here, though, plus one; for a total of 14 valence electrons for the BrO- Lewis structure. We'll put Bromine here, and then next to it, we'll put the Oxygen atom. For BrO-, we'll put two valence electrons between atoms to form a chemical bond. We'll go around the outside, 4, 6, and 14 valence electrons. So we've used all 14 valence electrons. The Bromine has 8 valence electrons, it has an octet. And the Oxygen also has an octet. One last thing we need to do to complete the BrO- Lewis structure is put brackets around our structure to show that it's a negative ion.

So that's the structure for BrO-. This is Dr. B., and thanks for watching.
