A rocket's engine applies a constant amount of force until it stops working. However, the rocket's acceleration increases as the engine pushes it into space. Which explanation for the rocket's motion involves Newton's Law of force and acceleration?

space exploration has led to the development and technological improvement of many everyday items. (if this answer is wrong i will find the right answer) : )

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.
