WebJun 2, 2024 · No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The periodic table is arranged in order of increasing atomic number, so the number of protons is the element number. For hydrogen, the number of ... WebApr 1, 2024 · There are 13 protons in an atom of aluminum, so the equation would be 27-13=14. Some atoms of aluminum do not have 14 neutrons. These atoms are called isotopes. Al-26 is an aluminum isotope with a half-life of 730,000 years. Al-28 has a much shorter half-life of 2.3 minutes. A neutral atom of aluminum also has 13 electrons.
