Determine the element that contains 15 neutrons and 13 protons.

Explanation:

In order to determine the element, we must first determine the atomic number and the atomic mass of the element. To do so, we refer to the formulas below.

Atomic number = number of protons = number of electrons

Mass number = Atomic Number + Number of Neutrons

Atomic Number = Mass Number - Number of Neutrons

Number of Neutrons = Mass Number - Atomic Number

Since we already have the number of protons, this means that the atomic number is 13.

Atomic Number = 13

Mass Number = 13 +15

Mass Number = 28

Based on the periodic table of elements, the element closest to these conditions is Aluminum (Al)

Final answer:

= Aluminum
