What is the least reactive element on the periodic …

the nobel gasses, like helium. reactivity is based on how easily an element loses its electron to achive a full valence shell. its like trying to get rid of or get dimes and quarters to get a full doller. but when you already have a full doller and dont have any extra change, why would you want to give away or ask for dimes and quarters. these are nobel gasses, elements that dont want to gain
