I is the central atom single bonded to the 4 Br atoms. I also has 2 lone pairs of electrons. It may also be written without showing the lone pairs on any of the electrons, but with a negative charge on the I atom instead (that's how it was on my homework).
The Lewis structure for bromine pentaflouride starts with a Br atom in the center. There are five single bonds coming off and a pair of dots. Each bond is attached to an F atom with a pair of dots on each unbonded side.
Br is an atom.
The Lewis structure of SbCl5 has the Sb in the center with 5 Cl molecules branching off like a star. The branches of the molecules should be drawn as straight lines.
Br is in the center with single bonds going out to each of the 3 surrounding oxygen. Br has 1 lone pair and each of the oxygens have three lone pairs.

I is the central atom single bonded to the 4 Br atoms. I also has 2 lone pairs of electrons. It may also be written without showing the lone pairs on any of the electrons, but with a negative charge on the I atom instead (that's how it was on my homework).
H - Br There should be one dot to the right of the Hydrogen atom(H), sharing a bond with a dot to the left of the Bromine atom (Br). Then add two dots on each other side of the Br. In total, there should be one dot around H and seven dots around Br.
The Lewis structure for bromine pentaflouride starts with a Br atom in the center. There are five single bonds coming off and a pair of dots. Each bond is attached to an F atom with a pair of dots on each unbonded side.
The dot and cross diagram, or Lewis structure, for hydrogen bromide is as follows: Place a Br atom in the center and single bond it to one H atom. The Br atom then has 3 lone pairs placed around it.
BrF3 does not follow the octet rule. Both Br and F have seven valence electrons, so the Lewis structure will have a total of 28 electrons, or 14 electron pairs. Br is the central atom, connected to each F atom by a single bond. 3 lone electron pairs will surround each F atom, and 2 lone electron pairs will be on the Br atom.
To draw the Lewis structure of OPBr3:P is center atom. Double bond oxygen to P and put 4 electrons on its outer shell. Then have a regular bond connecting the three Br to the P and give them 6 electrons on the outside.
.....Cl Br-C-Cl ....Br Single Bonds for all and 3 pairs of unbonded electrons on both Cl's and both Br's
Br- is a Lewis base.
Br is an atom.
Br- ion will have 8 valence electrons. So to write the Lewis structure, write the symbol Br, with 8 dots around it. Each dot will correspond to one electron.
Br H-C-Br Br Now imagine the top and bottom Br to have a single bond connecting them to the central Carbon. PS. Don't forget to fill in your octets around each of the Br, but not the H.
