It's simple.

the number of protons in an atom never changes. And also, the no of protons is its atomic number. if you look up the periodic table, you will find a number on the top - left corner of each of the boxes. This is the atomic number. No 2 same elements on the periodic table have the same atomic number. So, all you have to do is search for a box that has the number 13 on it.

and by the way ... the element which you're searching for is Aluminium
