A scientist stirred a substance into 100 g of water at three different temperatures until it stopped dissolving into the water. Examine the table of the scientist's recorded results. Trial 1 mass of substance Trial 2 mass of substance Trial 3 mass of substance 110 72 105 Room Temperature Cold 78 55 81 140 Hot 83 135 During which trial did the scientist most likely commit an error in the procedure? How do you know?​

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
