For the alkaline-Earth metals, atoms with the smallest radii have the:a) Highest ionization energies b) Lowest ionization energies c) Highest atomic masses d) Lowest atomic masses
For the alkaline-Earth metals, atoms with the smallest radii have the:a) Highest ionization energies b) Lowest ionization energies c) Highest atomic masses d) Lowest atomic masses
Final answer:For alkaline-Earth metals, atoms with the smallest radii have the highest ionization energies. Correct option is c.Explanation:In the context of alkaline-Earth metals, the atoms with the smallest radii have the highestionization energies. This is because ionization energy and atomic radii are inversely related.As atomic radius decreases, there's a greater pull between the electrons and the nucleus, so it takes more energy to remove an electron (i.e., ionization energy increases).For example, Beryllium (Be) is an alkaline-Earth metal with one of the smallest atomic radii and it also has a high ionization energy. On the other hand, Barium (Ba) has a larger atomic radius and a lower ionization energy.Learn more about Ionization Energies here:brainly.com/question/33907239#SPJ11...
