Which element/ion has the biggest atomic/ionic size in each of the following pairs? O-1 or O-2O-2Which element/ion has the biggest atomic/ionic size in each of the following pairs? Al or Al+3AlWhich element/ion has the biggest atomic/ionic size in each of the following pairs? Cu+1 or Cu+2Cu+1Electronegativity is the tendency for the atoms of the element to attract electrons when they are chemically combined with another element.As you move across a period from left to right the electronegativity of an element will increase.As you move down a group, the electronegativity of an element will decrease.The elements in group 18 do not have defined values for electronegativities.The highest possible value for electronegativity is 4.0.Pick the element with the higher electronegativity:Bror IKor CaLior CsPor Na
