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 Ci because the formula is CaCi.
B. The number of dots around Ca should be one because Ca has to transfer only one electron to CI.
C. The Ca atom should transfer only one electron to CI, and the second electron should be transferred to another CI atom.
D. The CI atom should transfer two electrons to Ca because it has more electrons than Ca, so formula becomes CaCI*2
