Presentation Transcript

  1. Aim: How do chemists calculate the average atomic mass? Essential questions: How are isotopes of the same element alike? Different? Describe the major differences between electrons, protons, and neutrons in terms of size, mass, and location. Why are the atomic masses in decimal form on the Periodic Table of the Elements if protons and neutrons are whole entities?

  2. Aim: How do chemists calculate the average atomic mass? Do Now: a) Write the isotopic notation for: U-235; Pd-106; Cs-133; Pb-208. • Determine the number of protons, neutrons and electrons for the elements above. • How does PupilPath calculate your grades?
