![]() ![]() To help show this three-dimensional shape even more accurately, we can rely on space-filling models as well as ball-and-stick models. We will discuss the significance of these electrons at the end of this section. ![]() In this article, we will discuss NBr3 lewis. It is highly unstable and can be hydrolyzed in water. In pure form, it is very explosive in nature. Nitrogen tribromide appears as deep red is a chemical compound having the molecular formula NBr3. The two dots above nitrogen indicate a lone pair of electrons that are not involved in any covalent bond. Solution Analyze: We are given the molecular formulas of a molecule and a polyatomic ion, both conforming to the general formula ABn and both having a central atom from the p block of the periodic table. Nitrogen tribromide (NBr3) lewis dot structure, molecular geometry, polar or non-polar, hybridization. However, in the more detailed structural formula on the right, we have a dashed line to indicate that the rightmost hydrogen atom is sitting behind the plane of the screen, while the bold wedge indicates that the center hydrogen is sitting out in front of the plane of the screen. In the structural formula to the left, we are only seeing a two-dimensional approximation of this molecule. Keep in mind, however, that atoms and molecules, just like everything else in the universe, exist in three dimensions-they have length and width, as well as depth. From both of these structural formulas, we can see that the central nitrogen atom is connected to each hydrogen atom by a single covalent bond. ![]()
