SiH4 Shape

Why is it that SiH4 has a molecular shape of tetrahedral and not a square planar?

Hybridization [ENDORSED]

On page 189 of our course reader, question 6A gives the Lewis structure for amino acid proline and asks for the hybridization for specific atoms of the structure. I am only able to get the hybridization of the nitrogen atom and the last oxygen atom on the far right. I have been using AXE to find hyb...

Re: order of ligand names [ENDORSED]

When working from name to the formula of a molecule, does the order matter? I know that if we are given the formula and then we are asked for the name we are require to write it in alphabetical order but how does it work if we are given the name first and we are trying to figure out the formula for ...

Bond Angles

When it comes to learning the angle of the shapes, will the angle always hold true to the specific shape? In other words, every time I identify a molecule as a Trigonal planar I should automatically assume its angles are 120, or t-shapes with angles 90 and 180

Re: Spin Magnetic Quantum Number [ENDORSED]

The fourth quantum number is used two indicate the orientation of the two electrons in each orbital. The possible values are +1/2 and -1//2. The fourth quantum number relates back to the Pauli principle that states that no two electrons in the same atom may have identical values for all four quantum...

Re: Empirical Formula Question about non-whole numbers [ENDORSED]

Remember that the empirical and molecular formulas can NOT have decimal/ fraction subscripts. Subscripts represent the number of atom it contains. It is not possible to have 1.5 atoms of N. However it should still contain the smallest whole number of each atom in the formula.

Re: Significant figures [ENDORSED]

The number of significant figures will depend on the problem. If I am not mistaken, I believe you look to your original problem and look for the number that has the smallest significant figure and go off of that. Significant figures don't take into account leading 0's. So 0.1 and 0.000001 are both 1...
