Problem
Most noble gases are not assigned electronegativity values on common scales. Which statement most accurately accounts for this practice?
(a) They are monatomic gases that always share electrons equally, so their electronegativity is effectively 0.
(b) They possess an unusually low effective nuclear charge compared with neighboring elements, preventing them from attracting bonding electrons.
(c) Their valence shells are completely filled, so they rarely form bonds in which electron-attracting ability can be measured.
(d) Their extremely high ionization energies make direct measurement of electronegativity impossible.
