CaCl2
Step-by-step explanation:
Calcium: Ca
Chloride or chlorine: Cl
Chloride: it is name of chlorine when it has a ion
calcium has a charge of +2 and Chlorine has a charge of -1
this is a ionic bond, so the charges of the two atoms have to equal or cancel out, so u need two Chlorine
and then it will be calcium +2 and chloride -2
2-2=0, they are neutral and we are right
CaCl2
