The numbers of protons and electrons in any neutral atom are the same as the atomic number, 13 for aluminum. The number of neutrons varies by isotope and can be found by subtracting the atomic number from the Atomic Mass number. One isotope is Al-27, in which there are 14 neutrons.
Aluminium is a metal element. Mass number of it is 27.
Alluminium is a metal element. Atomic mass number of it is 27.
The atomic number for Al is 13 and the atomic mass is 26.98.
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
Aluminum's atomic number is 13. Its atomic MASS is 25.98154.
The atomic number for aluminum (aluminium, symbol Al) is 13. This is the number of protons, also known as the "element number." Atomic mass/weight is 26.981 (most aluminum is 27Al) The atomic weight of Al is 26.981539 amu, and the molar mass 26.981539 grams per mole. (see also the related link below)
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.
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
The atomic number for aluminum (Al) is 13, and it has an atomic mass of 27.0
Aluminum's atomic number is 13. Its atomic MASS is 25.98154.
The gram atomic mass of aluminum, which is defined as the mass of Avogadro's Number of atoms of the element, is 26.9815. To the justified number of significant digits, this is the same as the gram atomic mass. Therefore, the mass stated in the question contains Avogadro's Number of atoms: to the justified number of significant digits, 6.02 X 1023.
Alluminium is a metal element. Atomic mass of it is 27.
Aluminum's atomic mass is 26.9815386,but if rounded up,it is 27.
The atomic number for aluminum (aluminium, symbol Al) is 13. This is the number of protons, also known as the "element number." Atomic mass/weight is 26.981 (most aluminum is 27Al) The atomic weight of Al is 26.981539 amu, and the molar mass 26.981539 grams per mole. (see also the related link below)
the symbol is Al and the charge is negative 3.
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.

Aluminum is useful for make alloys. It is a p block element. aluminum got 13 as atomic number.13
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.
