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
