Which of the following is a demonstration of Boyle's gas law? Bubbles exhaled by a scuba diver grows as they approach the surface of the ocean water increasing in volume.
Bubbles exhaled by a scuba diver shrinks as they approach the surface of the ocean water decreasing in volume.
Bubbles exhaled by a scuba diver stays the same as they approach the surface of the ocean water.

50.23 i believe is correct but don't quote me on that.

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.
