Atomic Theory:
One strength I had with atomic theory was understanding how isotopes were averaged out with each variation and their abundancy. I understood this through the noodilium lab, because the different noodles helped me have a visual understanding. I also finally understood the role that neutrons played in changing the isotope altogether.
One weakness I had was understanding the periodic trends in the periodic table. The sizes and charges confused me. And I had a hard time differentiating between the atomic radius and the ionic radius.
Bonding:
For Bonding, I was good at drawing and filling in info on the diagrams (lewis and VESPR). It was a bit difficult to understand at first, but I finally understood how the valence electrons/lone pairs affected the shape of the VESPR diagram. The lewis diagram was straight forward and made sense to me.
I think that the intermolecular bonding was a challenge for me though. Because I had a hard time understanding how the periodic trends affected the strength of each bond. It was also a challenge to understand that the electrons distribution was random, but they were also more likely to be attracted to the more electronegative atom(s).
The Mole:
One strength for me in this unit would be unit conversions it was easy for me to do them, since I already had so much practice in physics. I understood how to cross out units and I also understood how to use prefixes like “kilo” or “deci” to convert certain units.
One weakness for me in this unit was getting rid of fractional subscripts in the empirical formula. I had a difficult time understanding that 1.33 was the same as 1 1/3. I also think that I could have showed my work instead of doing in all in my calculator, which is how I got some answers wrong.
