Shameeka is studying for an exam. She took the notes below about calcium and chlorine, which are known to form ionic bonds. Calcium, which is a metal, donates 2 electrons to chlorine. The individual calcium atoms become ions with a negative 2 charge. The bond between calcium and chlorine makes the atoms stable. Calcium and chlorine attract each other. Which best describes Shameeka's error? Calcium is a metal, so it donates protons, not electrons. The individual calcium atom has a positive, not negative, 2 charge. The bond formed makes the atoms unstable, not stable. Calcium and chlorine repel, not attract, each other.
