The mass number (symbol A, from the German word Atomgewicht atomic weight), 1 also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. When you look at the structure of the atom, you have a dense, positive nucleus composed of protons and neutrons. Around the nucleus are a equal number of negatively charged electrons.

Explanation:
Mass number equals number of sub atomic particles in the nucleus.
Atomic Mass Equals The Number Of Protons And Neutrons
Atomic number gives the number of protons, which equals the number of electrons. The atomic number for oxygen is 8, so the atom has 8 electrons and 8 protons.
Protons and neutrons are found in the nucleus, so the number of neutrons is found by subtracting the proton number from the mass number I.e. 16 - 8 = 8
Oxygen exists in isotopic form and has an isotope with mass number 18. This atom will have 10 neutrons as 18 - 8 = 10
