14
The number of neutrons in an aluminum ion can vary depending on the isotope. The most common isotope of aluminum is 27Al, which has 14 neutrons. However, other isotopes of aluminum exist with different numbers of neutrons.
number of neutrons = mass number - number of protons = 28 - 13 = 15 neutrons
The atomic number of aluminum is 13, therefore there will be 13 protons.The number of neutrons equals the mass number minus the atomic number. For aluminum-25, that will be 25 - 13 = 12 neutrons.There will be 13 electrons in the neutral atom of aluminum, regardless of which isotope we are considering.
Number of neutrons = Mass number - Number of protons = 26 - 12 = 14 neutrons
Aluminum is 13 because that is the atomic number (the number of protons). The atomic mass number is the number of protons and neutrons in an atom. In this, you just subtract the number of protons from the mass number. If Aluminum (Al), #13, has a mass number of 27, then it has 14 neutrons. Pretty simple.
Well, honey, if you must know, the element aluminum-27 has 14 neutrons. So, next time you're at a trivia night and they ask you that question, you can thank me for making you look like a smarty pants.
Aluminium has 15 neutrons.
The isotope that has 13 protons and 14 neutrons is aluminum.
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.
The number of neutrons is irrelevant for determining the element. 13 protons makes it aluminum. (The isotope of aluminum with 13 neutrons is unstable and radioactive, with a half-life of about 720,000 years.)
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.
The mass number of aluminum is 27. This is calculated by adding together the number of protons and neutrons in the nucleus of an aluminum atom. Aluminum has 13 protons and typically 14 neutrons, resulting in a mass number of 27.
