Suppose a laboratory wants to identify an unknown pure substance. The valence electrons of the substance's atoms feel an effective nuclear charge of +7. If the unknown substance has lower ionization energies than chlorine (Cl), what other characteristics would you expect the substance to exhibit? (1 point)
It would have larger atomic radii than Cl and a higher electronegativity value than Cl. It would have larger atomic radii than Cl and a lower electronegativity value than Cl. It would have smaller atomic radii than Cl and a higher electronegativity value than Cl. It would have smaller atomic radii than Cl and a lower electronegativity value than Cl.
It would have smaller atomic radii than Cl and a higher electronegativity value than Cl.
