Odd One Out Chemistry Activity

I created this odd one out chemistry activity to give my students practice determining how the placement of an element on the periodic table tells us about how an element will likely behave.

For this activity, students were given three elements to locate on the periodic table. Based on these locations, they had to determine which element is least like the others. We glued the results in our chemistry interactive notebooks.

I vaguely remember thinking after I did this activity that one of the answers on my answer key was incorrect, but I can’t remember now which one it was. Sorry! This is what happens when I blog in 2021 about an activity I did back in the 2017-2018 school year.
