27. How many neutrons does it have?
OA. 13
B. 14
C. 27
D. 40

Answer 1

An atom of aluminum with an atomic number of 13 and a mass number of 27 will have 14 neutrons.

Step-by-step explanation:

An atom of aluminum (Al) has an atomic number of 13 and a mass number of 27. To determine the number of neutrons, subtract the atomic number from the mass number: 27 - 13 = 14. Therefore, an atom of aluminum has 14 neutrons.
