Does the Lewis structure of BH3 contain an atom that does not obey the octet rule?

BH3 does not obey octet rule.
it has a total of six electrons only.
boron has three electrons in the valence shell and it accepts one electron from each hydrogen
BH3 is a planar molecule and is found only in the gaseous state.
BH3 dimerises to form B2H6 with 4 terminal hydrogens attached by normal covalent bonds and 2 hydrogen bridges , 3 centre 2 electron bonds. Once again in the dimer it does not obey the octet rule.

∙ 12y agoIn borane (BH3) boron has three valence electrons. Even when bonded to those three hydrogens, it's still two electrons short of the octet.

After drawing a Lewis structure one should?
Count the electrons in the structure to be sure that the number of valence electrons used equals the number available.Be sure the central atom and other atoms besides Hydrogen have an octet.
What is the Lewis structure of an atom?
There is none because there are no bonds in an atom.
Lewis structure for compound C2N2?
The Lewis dot structure for cyanide has a C atom triple bonded to an N atom. each atom then has a pair of dots on the unattached sides.
What is the Lewis structure of carbononitridic chloride?
The Lewis structure of carbononitridic chloride, or NCCl is as follows: A N atom is triple bonded to a C atom. The C atom is single bonded to a Cl atom. The N has one lone pair and the Cl has 3.
Does BBr3 obey octet rule?
First, it helps to draw out the Lewis structure. Boron, being the least electronegative element is in the center, with the three Bromines singly bonded around it. Each Br has an octet of electrons (3 lone pairs plus the single bond) and there are no electrons left over to go onto the Boron. This leaves Boron without an octet, but Boron is an exception to the octet rule so that's okay. So, no BBr3 does not follow the octet rule.
What is a atom that forms a stable ion but not have an octet structure?
Helium; it has a duplet structure.

What is the concept of the Lewis model of the atom?
The Lewis structure of an atom gives a clear illustration of the valence electrons.
What is the octet rule and how is it used in Lewis dot structure?
Most elements have a stable electron arrangement when they have 8 electrons in their outer shell (hydrogen and helium are exceptions, they are stable with only 2 electrons in their outer shell), and an octet is 8 of something, hence the octet rule. Lewis dot diagrams are drawn to show how many electrons are associated with any given atom, and how the atoms are shared, in the case of covalent bonding. Generally, each atom winds up with 8 electrons. Not hydrogen.
