Q: How are effective nuclear charge (Z eff ), atomic radius, and 1st ionization ene

The answer is: As Zeff increases, atomic radius decreases, and 1st IE increases As effective nuclear charge increases => net positive charge on nucleus increases => attraction for negatively charged outermost electrons increases => (1) outermost electrons pulled closer to nucleus and (2) more energy required to remove outemost electrons => (1) atomic radius decreases and (2) 1st ionization energy increases

Question

How are effective nuclear charge (Zeff), atomic radius, and 1st ionization energy related?

As Zeff increases, atomic radius decreases, and 1st IE increases. There is no relationship between Zeff, atomic radius, and 1st IE. As Zeff increases, atomic radius increases, and 1st IE increases. As Zeff increases, atomic radius decreases, and 1st IE decreases. As Zeff increases, atomic radius increases, and 1st IE decreases.

Explanation / Answer

The answer is:

As Zeff increases, atomic radius decreases, and 1st IE increases

As effective nuclear charge increases

=> net positive charge on nucleus increases

=> attraction for negatively charged outermost electrons increases

=> (1) outermost electrons pulled closer to nucleus and (2) more energy required to remove outemost electrons

=> (1) atomic radius decreases and (2) 1st ionization energy increases
