2 answers:
Explanation :
Noble gases are the elements of group 18. This series contains helium, neon, radon krypton and radon.
The noble gases are the least reactive of any elements on the periodic table. This is because they have eight valance electrons in its outermost shell.
Non-metals or poly atomic ions forms acidic compounds with hydrogen. For example : etc forms acidic compounds with hydrogen.
The halogens are the most reactive among all the elements. This is because halogens suddenly combines with most of the metals. They are never seen uncombined in nature.
For example : Chlorine, fluorine and astatine are some halogens.

To calculate the change in kinetic energy, you must know the force as a function of position. The work done by the force causes the kinetic energy change
Explanation:
The work-energy theorem states that the change in kinetic enegy of an object is equal to the work done on the object:
where the work done is the integral of the force over the position of the object:
As we see from the formula, the magnitude of the force F(x) can be dependent from the position of the object, therefore in order to solve correctly the integral and find the work done on the object, it is required to know the behaviour of the force as a function of the position, x.
