On the basis of the electronic configuration, the three given elements are to be identified and their appropriate values of first ionization energies and atomic radii are to be matched. Concept Introduction: The distribution of the electrons that exists in the atomic orbital of an atom is collectively known as electronic configuration. The description of every electron in an orbital is given by the electronic configuration of that atom. According to the periodic table, the ionization energy of the elements increases while moving left to right in the period due to decrease in the atomic size. On the other hand, the ionization energy of the elements decreases while going down the group due to increase in the atomic size of the elements.

Experiment: Each team will be provided with 5g of a mixture of acetanilide and salicylic acid. You will divide it into three 1.5 g portions in separate 125 mL Erlenmeyer flasks savıng some for melting point analysis. Dissolve the mixture in each flask in ~60mL of DI water by heating to boiling on a hotplate. Take the flasks off the hotplate once you have a clear solution and let them stand on the bench top for 5 mins and then allow them to cool as described below. Sample A-Let the first sample cool slowly to room temperature by letting it stand on your lab bench, with occasional stirring to promote crystallization. Sample B-Cool the second sample 1n a tap-water bath to 10-15 °C Sample C-Cool the third sample in an ice-bath to 0-2 °C Results: weight after recrystalization and melting point temp. A=0.624g,102-115° B=0.765g, 80-105° C=1.135g, 77-108 What is the percent yield of A,B, and C.
