describe how calcium and chlorine atoms react to form calcium chloride?

Calcium atoms lose 2 electrons
Each chlorine atom gains 1 electron so 2 Cl must react with 1 Ca.

Calcium and chlorine....
When calcium metal is combined with chlorine gas with sufficient heat to initiate the reaction, chlorine atoms collide with solid calcium. A chlorine, with its high electronegativity, and unpaired electron attracts the valence electrons of calcium forming a highly polar bond. Ca-Cl bonds have about 68% ionic character. There is no complete transfer of electrons in solid CaCl2.
Ca(s) + Cl2(g) --> CaCl2(g)
Cl-Cl --> 2Cl•
Ca + Cl• --> CaCl^+
CaCl^+ + Cl• --> CaCl2(g)
CaCl2(g) rapidly forms a solid with a lattice of calcium and chlorine atoms. There are no molecules of CaCl2 in the solid state. CaCl2 is the empirical formula for the network solid.
