Could you give me a level 4 example of a prediction as a Hypothesis (in the form of an If... then... statement) and provide reasoning based on grade 12 (SCH4U) knowledge of electron configurations about the lab attached.

LAB EXERCISE 3.6.1 Quantitative Paramagnetism In Investigation 3.5.1, you obtained some preliminary evi- dence for a possible connection between unpaired electrons (as determined by the electron configuration) and paramag- netism. The purpose of this lab exercise is to test this hypoth- esis with a quantitative experiment. Question What effect does the number of unpaired electrons have on the strength of the paramagnetism of metal salts? Prediction/Hypothesis (a) Write a prediction and provide your reasoning based on electron configurations. Experimental Design A sensitive electronic balance is used to measure the attrac- tion between a powerful magnet and a test tube containing a metal salt. The balance is tared (zeroed) before the test tube is lowered (Figure 4). The mass reading is taken just before contact of the test tube with the magnet.
