REMEMBER:
Until now, all atoms have been electrically neutral with equal numbers of negatively charged electrons
and positively charged protons. However, atoms of an element often have different amounts of
electrons. However, they can NOT have different numbers of protons. Protons are unique to a specific
atom and element. Eight protons is oxygen and oxygen is eight protons; nothing else.
But what happens when an atom gains or loses an electron? An ion is formed. An fQjl is simply an atom
with an electrical charge; it has unequal numbers of negatively charged electrons and positively charged
protons. ff !t has more negatively charged electrons than positively charged protons it is a negatively
charged àrrtffi. lf il has more positively charged protons than negatively charged electrons it is a
positively charged deïlthîr.
