A student made the Lewis dot diagram of a compound as shown.
What is the error in the Lewis dot diagram?
a. The Ca atom should transfer only one electron to Cl because the formula is CaCl.
b. The number of dots around Ca should be one because Ca has to transfer only one electron to Cl.
c. The Ca atom should transfer only one electron to Cl, and the second electron should be transferred to another Cl atom.
d. The Cl atom should transfer two electrons to Ca because it has more electrons than Ca, so the formula becomes CaCl2.
