Jigsaw ActivityJigsaw Activity
There are several properties of the elements in the periodic table that vary in observable patterns.
In this jigsaw activity you will learn about trends in the following:◦Atomic Size (Radius) (p 31-34)◦Ionization Energy (p 34-35)◦Electron Affinity (p 35-36)◦Electronegativity (p 36-37)
