Other answers:

you're right...i think...Mg^2+ means that 2 electrons are missing (to give it that charge of +2) so that would make the overall radius (nucleus + electron orbit) smaller
#2: Which of the following has the lowest first ionization energy: Fr, F, Li, or Rb? A. Fr B. F C. Li D. Rb **My answer; C. Li is that right??? or is it A. Fr?? idk :/
