Now a string of islands at the southern-most end of Japan, Kikai caldera currently connects to four different volcanoes. And while the largest volcano, Mount Io, erupts continuously, these eruptions are small when compared to the 4350 BC eruption.

The number of protons an atom has in its nucleus is given by the atomic number. A quick looks in the periodic table will show that aluminium has an atomic number equal to #13#. This means that any atom that is an isotope of aluminium will have #13# protons in its nucleus. Since you're dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus. Therefore, the aluminium-27 isotope will have #13# electrons surrounding its nucleus. Finally, use the known mass number to determine how many neutrons you have.
