On top of Mt. Yale in Colorado (elevation 14,202 feet), you step on a scale and weigh 183 pounds, using the same scale in New Orleans (elevation 4 feet) you would weigh ?
A. More than on top of Mt. Yale
B. Less than on top of Mt. Yale
C. The same as on top of Mt. Yale

Please help.. an explanation would really help as well..

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.
