Bell work:
1) write the isotopic notation for the following (include charge)
an element with 31 protons, 28 electrons and 40 neutrons
2) write the electron configuration for germanium
CW: we went over the electron configuration worksheet and took notes on how group numbers and period numbers relate to valence electrons, we discussed noble gases and how other elements form ions to obtain their own noble gas configuration and we discussed electron dot structures
no work, just going over work and learning new info
Chapter 4-5 test next Tuesday - protons, neutrons, electrons, isotopes, calculating average atomic mass, ions, e- configurations, orbital diagrams, noble gas notation and electron dot structures
