For the reactions described in the following Questions 1 and 2 below, first write and balance the equation for the chemical reaction. Next, for each of these two reactions, answer the following questions. Make sure to explain every answer in details: (a) What substance is reduced? (b) What is the reducing agent? (c) What substance is oxidized? (d) What is the oxidizing agent? Question 1: Erbium metal (Er) can be prepared by reacting erbium(III) fluoride with magnesium; the other product is magnesium fluoride. Question 2: Europium (Eu) is used in older television screens to give a red color. The metal can be prepared by electrolysis of molten europium(III) chloride; chlorine gas is a by-product.

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.
