Because I (iodide) is better leaving group than Cl, so it will leave when this molecule is reacted with strong base (sodium tert-butyl oxide) giving the elimination product provided in picture<span />
A few elements with 1 valence electron are hydrogen (H), Lithium (Li), and sodium (Na)
Nuclear power plants real ease energy by FISSION
(this is the process when a heavy, unstable atomic nucleus splits into 2 or more lighter elements. This process releases lots of energy.)
I hope this helped you out! :)
