A common radioactive isotope of Carbon is C-14. How many protons, neutrons and electrons does it have? Draw the atom to answer this question.

 

 

 

 

Suppose that you have just discovered a new element and have named it neptunite. While studying your new element, you find that it has two isotopes, neptunite-220 and neptunite-250. What is the average atomic mass of your new element? (Assume that these two isotopes are present in equal numbers in nature)
