The valency of calcium is +2 in the compound CaCO3 or Calcium Carbonate.
It means that calcium atom has two free electrons in its outermost shell that is easily transferred to the CO3 or carbonate group, which has -2 valency or the space for 2 more electrons to complete the octet on the outermost shell.
