Answer:

Aluminum

Explanation

mass number = number of protons + number of neutrons

Number of protons = mass number - number of neutrons

No of protons = 27-14 = 13

Aluminum contains 13 protons

Answer:

the number of neutrons in above isotope = A - Z = 27 - 13 = 14. Note: The molar mass of aluminium, which is average of atomic masses of all isotopes = 26.981538 g/mol, since 13Al27 is the major isotope.
