Answer: The element is represented as Aluminium-27

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an electrically neutral atom.

Atomic number = Number of electrons = Number of protons = 13

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons = 13 + 14 = 27

Thus the element with atomic number of 13 is aluminium and its mass number is 27. Thus it is represented as Aluminium-27
