The Structure of an Atom

{ Atom and Isotope Review Physical Science. An atom has 6 protons, 8 neutrons, and 6 electrons. What is the atomic mass?

2. What are isotopes? Use two particles from the table above to illustrate your answer. (3 marks) 17 O & 18 O (1) Same Atomic mass / number of protons.

Isotopes and abundance. The relative atomic mass scale is now based on an isotope of carbon, carbon-12, which is given the value of amu.
