The VSEPR model predicts a linear shape for the N3- ion. The N3- ion is also known as Azide Ion and is found in the form of sodium azide contained in air bags of cars.

∙ 14y agoIt's electron geometry is tetrahedral but it's molecular geometry is pyramidal. Bond angles are less than 109.5 degrees. Because of the unpaired electrons (AB3E), it is polar. Partial positive charges on the bromine with unpaired electrons, and partial negative on the oxygen bonds. Central atom hybridization=sp3. For a picture, I would suggest an internet search for VSEPR AB3E.
Make the Lewis Dot structure and you will see that one pair of electrons is non-bonding. The repulsion between electron pairs is strongest between two non-bonding PAIRS of e-. But, the next strongest repulsion is between a bonding pair and a non-bonding pair. In the case of BrO3, the non-bonding pair is surrounded by two bonding pairs of e-. That is why the model shows the bonds angling away and down from the central atom instead of straight out.
Draw an arrow up from the Br atom through the non-bonded pair of e- to represent the most repulsive (tee hee) pair of e-. This is the "E" in AB3E.
Draw arrows out through the other 3 bonded pairs of e- and make them a little shorter to remind you why this molecular geometry is pyramidal in shape rather than merely tetrahedral. You should have 4 arrows pointing away from the Br; one bigger than the other three to represent the unbonded e-.

Can the VSEPR theory be used to predict the shapes of all molecule?
no, not all molecules obey the VSEPR theory, there is an exeption considered for the SIO2 molecules which obeys not the VSEPR theory
What does the vsepr theory give information about?
Valence shell electron pair repulsion theory is used to predict and explain the way that bonded atoms are arranged around the central atom to which they are joined. For instance, it explains why an ammonia molecule has a trigonal pyramidal shape rather than a flat one.
Explain how the VSEPR theory can be used to predict the shapes of molecules?
Valence electron pairs will move as far apart from each other as possible. (Apex)
How do Lewis structures help predict the shape of a melocule?
Look at double bonds and dotted valence. Double or more bonds equals a linear shape. Also... 2 bonds = linear 3 bonds = linear if dbl or trpl bonded, otherwise bent 4 bonds = triginal poly Etc.
What is the vsepr model mainly used for?
The VSEPR model is used mainly to determine molecular shape.

What is the vsepr theory used to predict?
According the VSEPR theory of molecular geometry, the geometry of SCl2 would be the same as H2O which is a bent angle
What in VSEPR theory?
VSEPR stands for Valence Shell Electron Pair Repulsion, and it describes how valence (bonding) electrons are arranged around an atom, and how they are used in creating a bond. This then can be used to help predict the GEOMETRIC SHAPE of the molecule being formed.
What does the VSEPR theory tell about a molecule?
A. The geometry it will have
What 2 theories can be used to predict molecular geometry?
VSEPR - valence shell electron pair repulsion theory Hybridisation- e.g. Sp, Sp2, sp3, Sp3d2 etc Hybridisation predicts regular geometries-- VSEPR has the advantage of predicting how bond angles may deviate from the regular geometries.
What is VSEPR theory used for?
Valence shell electron pair repulsion theory, otherwise known as VSEPR theory, is used to predict the geometry of molecules. This is based on the number of electron pairs surrounding their central atoms. This is based on the idea that valence electron pairs surrounding and Adam generally repel each other, so their arrangement is based on the minimizing of said repulsion.
What does the vsepr theory give information about?
Valence shell electron pair repulsion theory is used to predict and explain the way that bonded atoms are arranged around the central atom to which they are joined. For instance, it explains why an ammonia molecule has a trigonal pyramidal shape rather than a flat one.
What are the drawbacks of VSEPR theory?
The VSEPR theory is simple yet powerful. Nevertheless, like any simplified model, it has its limitations. First, although it predicts that the bond angle in H2O is less than the tetrahedral angle, it does not make any attempt to predict the magnitude of the decrease. Second, the theory makes no predictions about the lengths of the bonds, which is another aspect of the shape of a molecule. Third, it ascribes the entire criterion of shape to electrostatic repulsions between bonding pairs, when in fact there are numerous contributions to the total energy of a molecule, and electrostatic effects are not necessarily the dominant ones. Fourth, the theory relies on some vague concepts, such as the difference in repelling effects of lone pairs and bonding pairs. There also are some species for which VSEPR theory fails. Nevertheless, despite these limitations and uncertainties, VSEPR theory is a useful rule of thumb and can be used with reasonable confidence for numerous species.l
