No prep complete lesson to teach students how the number of protons, neutrons and electrons in an atom are calculated along with what isotopes are and how the relative atomic mass of isotopes is determined.
Includes interactive PPT with 5 page worksheet teaching students atomic number, mass number, isotopes and relative atomic mass along with self assessment and extension exercises
• Be able to define (a) atomic number, (b) mass number, © isotope and (d) relative atomic mass (Ar)
• Be able to calculate the number of protons, neutrons and electrons using an element’s atomic number and mass number
• Be able to work out which isotope is most abundant when given the mass numbers and Ar
