To answer this question, let’s recall the theory of the structure of atoms and how this information is displayed in the periodic table.

An atom consists of a nucleus and electrons revolving around it. The nucleus is made up of protons and neutrons. As a rule, the number of protons and electrons is the same and corresponds to the ordinal number in the periodic table.

The mass of a proton and a neutron is considered equal and conventionally equal to one. The total number of protons and neutrons in the nucleus constitutes the bulk of the atom of the element. The atomic mass of aluminum is 27, which means the sum of protons and neutrons is also 27.

The number of protons in an atom is equal to the number of electrons and is equal to the ordinal number of the element. This means that the number of neutrons is 27-13 = 14.

Answer: there are 14 neutrons in the aluminum nucleus.
