О в. 14
O C. 26
D. 27
E.

Answer 1

The number of neutrons in aluminum (Al) with an atomic number of 13 and a mass number of 27 is 14 neutrons.

Step-by-step explanation:

The number of neutrons in an atom can be determined by subtracting the atomic number from the mass number. In the case of aluminum (Al), with an atomic number of 13 and a mass number of 27, we subtract 13 from 27: 27 - 13 = 14 neutrons.
