I'm having trouble understanding the simple "planetary" model of the atom that I'm being taught in my basic chemistry course. 

In particular, 


I can't see how a negatively charged electron can stay in "orbit" around a positively charged nucleus. Even if the electron actually orbits the nucleus, wouldn't that orbit eventually decay? 
I can't reconcile the rapidly moving electrons required by the planetary model with the way atoms are described as forming bonds. If electrons are zooming around in orbits, how do they suddenly "stop" to form bonds.




I understand that certain aspects of quantum mechanics were created to address these problems, and that there are other models of atoms. My question here is whether the planetary model itself addresses these concerns in some way (that I'm missing) and whether I'm right to be uncomfortable with it. 


Question: 100% Rye Pizza Base Recipes?
Answer: 
  I don't mind experimenting a bit to find a recipe that works, but I could use some ideas on where to start - what sort of ingredients might bind the rye so that it doesn't crumble as a thin pizza base and maintains a low glycemic index for my diabetic wife.


Psyllium husk is the general go-to binder for low-carb bread, but I have not seen a recipe using it in rye pizza dough. Another alternative is to give up on substituting bread and use the same toppings with something else. A frittata does not add much extra work and works well with standard pizza toppings.
