  6. Homework Review 1. P: 1s22s22p63s23p3 Ni: 1s22s22p63s23p64s23d8 Au: 1s22s22p63s23p64s23d104p65s24d105p6 6s24f145d9 Unit 1 • Investigation III

  7. Unit 1 • Investigation III

  8. Question 3 • The last three electron configurations all have similar valence electrons 3s23p5 4s24p5 5s25p5 because they all have 7 valence electrons and are in the same group/column. They are halogens. Unit 1 • Investigation III

  9. Noble Gas Electron Configuration 10/28/10 • The noble gas electron configuration of an element starts with the noble gas that comes before the element in brackets and then continues from there to the element. • Ex. For the element Ca, that would be [Ar]4s2 • The valence electrons are the highest level electrons. For example, if the configuration is [Kr]5s24d105p4 , the valence electrons are 5s25p4 . Unit 1 • Investigation III
