Suppose a laboratory wants to identify an unknown pure substance. the valence electrons of the substance's atoms feel an effective nuclear charge of +4. if the unknown substance has a higher electronegativity value than silicon (si), what other characteristics would you expect the substance to exhibit?
it would have larger atomic radii than si and higher ionization energies than si.
it would have larger atomic radii than si and lower ionization energies than si.
it would have smaller atomic radii than si and higher ionization energies than si.
it would have smaller atomic radii than si and lower ionization energies than si.
