E2: Electrons and Solution Color
Is salt solution color predictable based on:• the position of the metal ion’s element in the
periodic table?• the metal ion’s electron configuration (Fig. 3, p. 223)?• the metal ion’s ionic radius (Ionic Sizes, p. 255)?• Its absorption and transmission of visible light?
Where are moles represented on the periodic table?

Mole of H2O = _____grams?
Molar Reflections*
Yesterday I took a drink of water And something strange happened in my head I made an actual connectionWith something that my chemistry teacher saidI could visualize lots and lots of moleculesMovin in the water to and fro…and then I thoughtIf I just drank 18 grams of waterI just drank a
Molar reflections, my mind is running freeMaking connections between the world and chemistryA mole is more than a number, more than just a wordIt’s an amount that’s equal to
