Reactivity QC:
which element would have the lowest electronegativity?

answers~ 1-an element with a small number of valence electrons and a large atomic radius, 2-The group with helium at the top, 3-an element will be more reactive if it has a very high or very low electronegativity, 4-fluorine, 5-an element with a high electronegativity and an element with a single valence electron
(if you use these you’ll get 100%)
