When an object travels no distance in a large amount of time, the object's speed is a. fast b. slow c. zero

zero because its not going anywhere its stationary

hope this helped ^_^

C, I believe. If it doesn't travel any distance, then it's speed should be zero, unless it is trying to travel against a conveyor or something.

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.
