Marking this solved. Title: Re: An isotope of Oxygen has 8 protons, 10 neutrons, and 8 electrons. What is the at Post by: mattjohnson0715 on Feb 11, 2014 Atoms of the same kind have the same atomic number. However, it is the mass number that can change among atoms of the same kind. These are called isotopes.
So, an oxygen with 8 protons and 10 neutrons (2 more from the 8 in normally has) has an atomic mass of 18 |
