Phases of molecules

Postby victoriatanaka1C » Sun May 20, 2018 12:23 pm

In Friday, Dr. Lavelle was explaining that the increasing strength of dispersion forces explains why F2 and Cl2 are gases at room temperature while Br2 is a liquid and I2 is a solid. He also gave other examples. In the periodic table we look at in class, it says the phases of atoms, but in the periodic table we got for the midterm, it didn't. Should I plan to memorize these phases?

On the periodic table, the elements are in groups in which they exist. For example, you'll notice that the right side are noble gases and in the center of the periodic table there are metals. It is not necessarily memorization but remembering how the periodic table is structured!
