I was wondering if someone could help me out with this question:
Give the symbol, including mass number and atomic number, for the isotope which has a mass number of 34 and which has 18 neutrons in each nucleus.
I originally thought about finding the atomic number which is 34-18=16. And then thought about Oxygen and O-zone. Can they be distinguished as two different sorts of elements due to them being formed as radicals? Or have I got this question totally wrong? Thanks for your help.
