Is aluminum atomic weight rounded to 26 or 27?
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.
What is the unit of an atomic mass for aluminum?
The unit of atomic mass for aluminum is atomic mass unit (amu) or unified atomic mass unit (u).
How can you find the number of neutrons that are in the nucleus of an atom?
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.
