This is a ppt designed for the teacher to do with the students. The idea is you pause and wait for students to make guesses. They have a copy of a blank periodic table to fill in as you do this with them.
#2:The point of this presentation is for you to put up an example, then pause. After each example, ask if they see a pattern. They should not see a pattern here yet because there is only one example.
#3:Ask, what do you think this electron configuration ends with?
#14:See a pattern yet? Well…how about those of you who do help out the rest of us.
#15:Ask, what is the letter and superscript of all of the electron configurations that are in this column?
#16:Does this surprise you? Ready for more? See the pattern yet?
#17:So what does the last part of the electron configuration start with for this ROW? (Yes I know the d’s will be different…but we’re concentrating on the main block elements at this point.)
#18:You may want to point out that there are some still left blank in the row…
