Question 4
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?
A. Calcium is a metal, so it donates protons, not electrons.
B. The individual calcium atom has a positive, not negative, 2 charge.
C. The bond formed makes the atoms unstable, not stable.
D. Calcium and chlorine repel, not attract, each other.
