Periodic Trends — Quiz
Test your understanding of periodic trends with 5 practice questions.
Practice Questions
Question 1
Using Slater's rules, what is the effective nuclear charge $Z_{eff}$ experienced by a 4p electron in a bromine atom (Z=35)?
Question 2
In a periodic trend analysis, if $Z_{eff}$ increases by 15\\% and atomic radius $r$ decreases by 5\\%, by what factor does the Coulombic attraction $F$, proportional to $Z_{eff}/r^2$, change?
Question 3
Why is the first ionization energy of oxygen lower than that of nitrogen despite oxygen being to the right in Period 2?
Question 4
Which species has the largest ionic/atomic radius in the isoelectronic series Ne, F$^-$, Na$^+$, and Mg^{2+}?
Question 5
A certain element shows a large jump in ionization energy between the third and fourth ionization energies. To which group in the periodic table does this element most likely belong?
