Designate with Roman numerals the valence of elements in compounds with chlorine, knowing that in these compounds it is monovalent KCl CaCl3 FeCl2 PCl5 ZnCl2 CrCl3 SiCl4
КСl – K = I, Cl = I,
CaCl3 – Ca = III; Cl = I,
FeCl2 – Fe = II; Cl = I,
PCl5 – P = V; Cl = I,
ZnCl2 – Zn = II; Cl = I,
CrCl3 – Cr = III; Cl = I,
SiCl4 – Si = IV: Cl = I.
