For each volume NaOH, determine the following and record in the data table. 1. Total volume of solution after NaOH is added. (The beaker starts with 15.00 mL HCI)
2. The ion in excess. There is no excess ion at the equivalence point, so leave it blank at that volume.
3. The moles excess reactant (use stoichiometry).
4. The molarity of excess reactant.
5. pH of solution

c. 75.7

i think that is the right

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.
