Question
An atom of 16 oxygen or oxygen-16 contains 8 protons, 8 neutrons, and 8 electrons. If it gains a neutron, what will it become?Group of answer choicesA negative ionAn isotopeA positive ionA neutral atom
Solution
The atom will become an isotope. When an atom gains or loses neutrons, it becomes an isotope of its original element. In this case, oxygen-16 gaining a neutron would become oxygen-17, an isotope of oxygen.
