Tuesday recap
Honors: we explained the relative sizes of cations and anions to their respective atoms; then we explained the periodic trends in first ionization energy across a period and down a group; we also explained the unforeseen anomalies to this trend in terms of electron shielding and repulsion. We then began to explain the trend in successive ionization energies.
We just have to finish that and cover electronegativity and electron affinity trends and then we will know just about everything that causes "chemistry" to occur.
We will apply this knowledge in our next unit: chemical bonding and attractions.
Regents: we reviewed for the multiple-choice exam tomorrow. The exam covers the entire periodic table unit which necessarily requires knowledge of atomic structure and electron configurations.
Then, we discussed the two types of chemical bonds: the ionic bond (which you will see in salts) and the covalent bond (which you will see in molecules).
AP: put the periodicity unit to bed and launched right into our unit on bonding and attractions. This is the ultimate unit in explaining practical things in chemistry. In this unit, we also get to do molecular geometry and relate that to molecular polarity. Soon, you will see that you can figure out things in seconds that, in the beginning, required minutes.
Big fun, basically.
