Which of newton’s laws of motion best relates to gravity and air friction working against each other to create terminal velocity? explain.

every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change by force impressed on it

Explanation:

Before release: object in a state of rest, airspeed is at zero, weight but no drag

When object is released: Object accelerates - the airspeed increases

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.
