Locate \(\mathrm{F}\) and \(\mathrm{Cl}\) on the periodic table. a) Describe any relationship between the core charge of these atoms, the number of valence electrons, and their position in the periodic table. b) Describe any relationship between the valence shell of these atoms and their position in the periodic table. c) Within our model and referring to the Coulombic Potential Energy expression, explain why the \(\mathrm{IE}_{1}\) of \(\mathrm{Cl}\) is less than that of \(\mathrm{F}\).
How does the core charge on the neutral atom change as we move from left to right across a row (period) of the periodic table?
Use the core charge concept to propose an explanation for the increase of \(\mathrm{IE}_{1}\) from Na through Ar. Clearly state any assumptions that you make.
How does the core charge for Na compare to the core charge for Li?
Within our model and referring to the Coulombic Potential Energy expression, explain why the IE increases from left to right across a row of the periodic table.
