well buddy im gonna tell u trick on how to calculate it .....
Geometry = 1/2 of ( valence e + number of monovalent atoms + charge on anion - charge on anion )
eg here valence e on central atom (here N) = 5, monovalent atoms = 0 ( oxygen is divalent ) , charge = -1
geometry = 1/2 ( 5 + 1) = 3
i.e sp2 trigonal planar
hope u know 2 = sp = linear
4 = sp3 = tetrahedral
5 = sp3d = trigonal bipyramidal
Easiest & quickest way to calculate !!!!! No need of even knowing the concepts :P
trigonal planar
Molecular geometry refers to the arrangement of atoms in a molecule in three-dimensional space, taking into consideration the position of all atoms and lone pairs. Electronic geometry, on the other hand, refers to the arrangement of electron pairs around a central atom, including both bonding and non-bonding pairs. In many cases, the electronic geometry may differ from the molecular geometry due to the presence of lone pairs.
(NO3)- has three single bonds.
The formula for the salt containing both Ca and NO3 ions would be Ca(NO3)2. This is because calcium (Ca) has a 2+ charge and nitrate (NO3) has a 1- charge, so to balance the charges, you need two NO3 ions for each Ca ion.
The formula for the ionic compound formed by magnesium ions (Mg2+) and nitrate ions (NO3-) is Mg(NO3)2. The formula for the ionic compound formed by calcium ions (Ca2+) and nitrate ions (NO3-) is Ca(NO3)2.
Trigonal Planar Electronic Geometry Geometry of Molecules: Trigonal Planar Three oxygen atoms are joined to the nitrogen atom in the NO3- ion to create a center atom. The configuration is trigonal planar, and the three oxygen atoms' bonds to the nitrogen atom have roughly 120-degree angles.
What is the electronic geometry of Bi_3? Enter the ... Thus, the total number of electrons in the molecule will be 24. There are no lone pairs in boron. Three electron domains are thus present in this molecule. Therefore, the electronic geometry of B I 3 is trigonal planar.
