Short Answer/Problems
2. A classmate insists that sodium will gain a positive charge when it becomes an ion because it gains a proton.
Explain why this statement is false.
Atoms can not gain or lose protons to become an ion, they can only gain or lose electrons. In this case, this
atom has lost electrons to gain a positive charge…there are more positive protons in the nucleus than there
are negative electrons…therefore the overall charge is positive.
