The number 6 refers to the atomic number c. The numbers 12, 13, and 14 refer to the mass number d. How many protons and neutrons are in the first isotope? 12 e. How many protons and neutrons are in the second isotope? 13 f. How many protons and neutrons … Freezing and Boiling Points - CliffsNotes So, the concentrations of the ions are . Al 3+ = 0.268 molal . Br – = 3(0.268) = 0.804 molal . Al 3+ + Br – = 1.072 molal . The total concentration of ions is four times that of the salt. When calculating the change in freezing point or boiling point, the concentration of all the solute particles must be used, whether they are molecules or ...

Ninth grade Lesson History of the Atom | BetterLesson To elaborate on the idea of models and atoms I have students work with partners on a worksheet where they read through five different models of atoms (A through E) and then compare the models to each other. This part of the lesson was adapted from Living By Chemistry's lessons on the atom. Living By Chemistry is a great book that often leads students …
