The Lewis structure of BrF3 is started by writing Br in the center. Three dashes are drawn from the Bromine atom with a Fluorine atom connected to each dash. On the unconnected sides of each Fluorine atom, two dots are drawn to represent the unshared electrons.
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).
It would look something like this .. .. .. : F ----Br -----F: .. .. .. There are 21 valence electrons in neutral BrF2, so there will be one unpaired. Draw each F having a shared pair, giving each F 8 electrons. The central Br atom will have 9 electrons. If the charge is BrF2 there will only be 8 electrons around Br, if the charge is BrF2- then there will 10. BrF2+ is well known.
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.
Two lone pair on the central selenium and three lone pairs on each chlorine. So total of eight lone pairs.
The Lewis structure for AlBr3 consists of three bromine atoms bonded to a central aluminum atom by single bonds. Aluminum has three valence electrons and each bromine contributes one electron, resulting in a full outer shell for aluminum and a complete octet for each bromine atom.
The Lewis structure of CHBr3 can be drawn with carbon as the central atom bonded to three hydrogen atoms and one bromine atom. The carbon-bromine bond is represented by a single bond with three lone pairs on bromine, making the bromine atom negatively charged.
The Lewis structure of BrF3 is started by writing Br in the center. Three dashes are drawn from the Bromine atom with a Fluorine atom connected to each dash. On the unconnected sides of each Fluorine atom, two dots are drawn to represent the unshared electrons.
The Lewis Dot structure for NaBr consists of Na with one valence electron and Br with seven valence electrons. The Na atom will transfer its electron to the Br atom to form an ionic bond, resulting in Na+ and Br- ions.
The Lewis structure of CCl2Br2 consists of one carbon atom bonded to two chlorine atoms and two bromine atoms. The central carbon atom is double bonded to one chlorine atom and single bonded to the other chlorine and two bromine atoms. The electron pairs are arranged around each atom to satisfy the octet rule.
Oxygen is the center atom with bromine on one side and hydrogen on the other. Oxygen has 2 loan pairs of electrons, bromine has 3 loan pairs of electrons, and hydrogen has none.
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.
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).
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.
likely it would form the +2 ion (the mercury), so put the Hg in brackets, with a +2 charge at the top right corner out side the bracket. put a bromine, with 8 electrons, in a bracket, with a -1 charge at its top right outside the bracket, and then do it again. formula has to be HgBr2. if it's the Hg+1 ion, do the same as I just wrote, but only include one bromine ion
The dot structure for bromine dioxide starts with a Br atom in the center. To the left and right is a singly bonded O atom, each with a pair of dots on the three unbonded sides. The Br atom has a pair of dots on the upper and lower unbonded sides.
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.
