lick the link here to open the atom-building interactive, and click the atom square. Use the interactive to answer the following questions. Note: Keep all atoms neutral (net charge = 0) for this exercise. Be sure to select the "plus" sign to expand the element, mass number, and net charge windows.

Make a He atom with a mass of 4. How many protons did you put in the nucleus?

Make a Li atom with a mass number of 7. How many electrons did you place in the outermost orbital (ring)?

Make a N atom with a mass number of 14. How many neutrons are in the nucleus?

Make a B atom with a mass number of 11. How many electrons did you put in the second orbital (ring)?
