Read "embankment dam at a gold mine." of the two opinions to consider in this case, which one presents a stronger argument? how does that you make your final decision as the consulting dam engineer? what was your decision for this dam, as the consultant? how can you accomplish this and still stay within your budget? (site 1)

The mayor presents a stronger argument because he is concerned over the safety of the citizens. If the gold mine isn't as productive as it used to be, yet is still being used, then the dam should be repaired or replaced in some manner. For the safety of the village & for the continuation of the gold mine, my decision would be to repair the dam. To keep the budget cost low, I would only repair what is needed to be fixed.

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.
