1) Write a program that prompts the user to enter an integer number one-to-five (numbers represent the first five elements in the periodic table) or enter a negative number to quit. Read in the integer. Error check to see if the number is with-in bounds (one-to-five) - if out of bounds print an error message and start over again, else print out the name of the element.
