what do the asterisks in the molecule stand for?
Context
Because the structure your nephew has copied is a polymer, it is a huge chain of repeating units. There are so many units in the chain that you actually can't draw all of them. An inidcation ...

Hybridisation/bonding of XRn oxides
Hybridisation is not a necessary concept to be introduced in these molecules if you want to explain their geometry. It is sufficient to admit that lone pairs are more cumbersome than sigma bonds.

Bond length data in ClF5
Octahedral molecular geometries can result in equidistant atoms, as you state. However, while the electron domain geometry is octahedral, the molecular geometry is actually square planar. Ideally, ...

Bond length data in ClF5
Axial bonds are closer to equitorial bonds. Axial bonds are 90 degrees from equitorial bonds while equitorial bonds are 120 degrees from axial bonds. This means axial bonds exhibit more electron ...

Resonance structure of aromatic [S4N4]2+
First, we verify the electron count. Four nitrogen and four sulfur atoms have a total of 44 valence electrons. Subtracting two for the charge and using sixteen pairs to form the sigma bonds and in-...

How to interpret the geometry of NO2 using VSEPR and orbital hybridization?
NO2 is sp2 hybridized. The best guidance I can find is that NO2 would be AX2E1/2. Since 1 electron counts as a half an electron pair. When determining hybridization and geometry, you generally count ...

Evidence of composition of water molecules?
In 1800, Cavendish discovered that water wasn't an element but rather a compound by burning hydrogen and oxygen to produce water. He enclosed hydrogen and oxygen in a tube and combusted it to give ...

Geometry of AsF5 molecule
We can predict the trigonal pyramidal geometry from electrostatic considerations. To wit, since arsenic is a metalloid its bonds with fluorine are quite polar, and we could expect the negatolively ...
