Question

Properties of the Alkall Metals& Halogens Atomic Element Radius lonization Energy Angstroms) Alkali Metals Li Na 2.05 2.23 2.77 2.98 3.34 124 119 100 96 90 Rb Cs Fr Halogens 0.57 0.97 1.12 1.32 1.43 Ci 299 Br 241 At Fr & At are extremely rare - they exist only in trace amounts Using the data above, graph (line graph) the following data. Use element symbols on x-axis instead of atomic number. Give each graph a title and label both the x- axis and the y-axis. Connect your points. Predict the plot points for elements with questions marks. 1. Atomic Radius(y) vs. Alkali Metals(x) arranged in increasing atomic number. 2. Ionization Energy (y) vs. Alkali Metals(x). 3. Atomic Radius(y) vs. Halogens(x). 4. Ionization Energy (y) vs. Halogens(x).

Explanation / Answer

1. Li < Na < K < Rb < Fr < Cs
2.Cs < Fr < Rb < K < Na < Li
3. F < Cl < Br < I < At
4. At < I < Br < Cl < F

ionization energy is indirectly propotional to atomic radius
that means as atomic radius increases ionization energy decreases

Cs has more atomic Radius than Fr is because effective nuclear charge
of Cs is less than that of Fr

i hope this explanation will help u solve the question
