Imagine your homework assignment involves identifying an unknown pure substance. The valence electrons of the substance's atoms feel an effective nuclear charge of + 1. If this substance's atoms have larger radii than potassium (K) atoms, what other characteristics would you expect the substance to exhibit?

It would have higher ionization energies than K and a higher electronegativity value than K.

a.) It would have higher ionization energies than K and a lower electronegativity value than K.

b.) It would have lower ionization energies than K and a higher electronegativity value than K.

c.) It would have lower ionization energies than K and a lower electronegativity value than K.

d.) It would have higher ionization energies than K and a higher electronegativity value than K

Nicholas · Answer 1

I f the unknown has a larger radius the valence electron is further away from the nucleus than in the K atom so it is more easily lost so ionisation energy must be lower and have a lower electronegativity.

CH2O and (3xCH2O)

PbCl2 and PbCl4 - two different compounds

NO2 and (2xNO2)

(3xCH4) and CH4 Remember the empirical formula is the simplest formula which shows the ratio of the constituent atoms
