Answer: 15
Explanation:
To find the atomic mass, you add the number of protons and neutrons. The number of electrons is the same as the number of protons
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
