Aluminium or aluminum (they're the same element, just spelt and pronounced differently depending on where you are from)
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
Aluminium is a metal element. Atomic mass of it is 27.
Aluminium is a metal element. Atomic number of it is 13.
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.
Sodium is a metal element. Mass number of it is 23.
The element with mass number 27 is cobalt, which has 27 as its atomic mass.
The only element with a radioactively stable isotope with a mass number of 27 is aluminum.
The atomic weight of aluminium is 26,981 538 6 (8), after IUPAC 2009. The mass number is the total number of nucleons (protons an neutrons) in the nucleus; the mass number is different for each isotope: For the stable isotope 27Al the mass number is 27.
Aluminium is a metal element. Atomic mass of it is 27.
Aluminium is a metal element. Atomic number of it is 13.
The mass number is 59; this element s cobalt.
Alluminium is a metal element. Atomic mass of it is 27.
Alumininum is a non metal element. Atomic mass of it is 27.
Alluminium is a meta element. Atomic mass of it is 27.
Cobalt is a metallic element. Mass number of it is 58.

The mass of an atom is primarily determined by the sum of its protons and neutrons. To find the mass of an atom with 13 protons and 14 neutrons, add the total number of protons and neutrons together: 13 protons + 14 neutrons = 27. The approximate mass of this atom would be 27 atomic mass units (amu).
