Aluminium has roughly a couple dozen isotopes; but the only one both stable and naturally occurring has 14 neutrons (mass number of 27).
Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons
Sodium-24, magnesium-25 and aluminium-26 atoms have 13 neutrons each.
The atom in question has 13 protons, so is atomic number 13, which is Aluminium. Assuming that all of the atom's mass is formed from the protons and neutrons, and each of these have atomic mass 1, the number of neutrons is 27 - 13 = 14 neutrons. Almost all Aluminium is of this isotope.
Atomic No. 13 belongs to the metal Aluminium which has 13 electrons, 13 protons and 14 neutrons in its normal state.
In its key isotopes there are 107 or 108 neutrons.
Aluminium-27 has 14 neutrons.
31
Nitrogen 7 protons, 7 neutrons and 7 electrons Aluminium 13 protons, 14 neutrons and 13 electrons
Aluminium has 13 electrons and protons; the isotope 27Al has 14 neutrons.
Aluminium has 15 neutrons.
Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons
In the Periodic Table aluminium is described as [27/13]Al 27 is the atomic mass ; the total of all the neutrons protons (nucleons) 13 is the atomic number ; the total of all the protons in the nucleus. Hencethe total neutrons is the mass subtracted from the number. 27 - 13 = 14 is the total number of neutrons in aluminium.
Aluminium has 13 protons and 14 neutrons. Giving aluminium an atomic number of 13 and an atomic mass of 27.
This isotope is aluminium-27.
Sodium-24, magnesium-25 and aluminium-26 atoms have 13 neutrons each.
as far as i know aluminum is a molecule not an atom. The aluminum atom has a valence of 3, what its chemical structure is depends on what it combines with.
The isotope that has 13 protons and 14 neutrons is aluminum.
