Si, other wise known as Silicon has 14 neutrons!
Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.
carbon-14
an atom of an element that does not the comman number of electrons is an isotope. for example cabon-12(has 12 neutrons) is a very common element but carbon-14(has 14 neutrons) is much rarer
Silicon
The Most common isotopes of elements with 14 & 15 neutrons are, respectively, silicon & phosphorus.
The element with 6 protons and 8 neutrons is carbon-14, which is a radioactive isotope of carbon.
A silicon-28 atom has 14 protons, 14 neutrons, and 14 electrons. The number of protons determines the element (silicon in this case), the sum of protons and neutrons gives the atomic mass of the isotope (28 in this case), and the number of electrons balances the charge to make the atom electrically neutral.
Nitrogen
The element aluminum (Al) typically has 14 neutrons. This can be determined by subtracting the atomic number (13) from the atomic mass (27) of aluminum, as the atomic mass includes both protons and neutrons.
Silicon
The number of neutrons is 8 (carbon-14).
Carbon is element number 6 and so has 6 protons so 14 - 6 means it has 8 neutrons
