Re: Which shapes to memorize

Inderpal Singh 3B wrote:Would we have to memorize the bond angles as well?

I don't think we would have to memorize bond angles for each one but you should know the general idea about how each shape looks and be able to deduce from there what the values of the angles are around (for example 90 vs less than 90 degrees).

Re: Lone Pair E-

Yes, lone pairs are considered their own regions and they repel other regions strongly too. That is why when looking at the shape of molecules we have to consider lone pairs (because they repel the other bonds).

Re: Bond Length & Strength Comparison

When you have this, I believe you use the radius of the atoms to see which one has a stronger bond. Since F has a smaller radius than Cl it will have a shorter bond and therefore be slightly stronger.

Re: How to utilize formal charge

You should use formal charges to check if what you are drawing is the most stable it can be. You want to prioritize formal charges of 0 as that is the most favorable. You also want to make sure that if there is a formal charge for example of -2 total, that it is spread across the structure evenly. F...

Re: Ionization Energy

A cation pulls in an electron much more and therefore it requires more energy for it to be removed. After the first ionization, the atom loses a negative charge and therefore it becomes positive making the nucleus stronger requiring more energy for the next removal.

When you have more protons, the nucleus pulls on the electrons making it smaller despite possibly a larger amount of electrons. So the ion with the least protons will have the largest radius.

Make sure to convert your units! The best way to check is to cancel out the units that you can and make sure to include them in your work (instead of just manipulating the numbers). This way you will know what values you may need to convert and you can find any mistakes more easily.
