how do you think the size of an atom will affect its ability to attract additional electrons?; in which section of the periodic table are the most active metals located?; which sequence correctly places the elements in order of increasing ionization energy?; which group has high ionization energies but very weak electron affinities and why; which characteristics both generally decrease when the elements; which element is an alkali metal?; which electron-dot symbol represents the atom in period 4 with the highest first ionization energy; do metals have high electronegativity
