The formula is H 2 O so the dot and cross diagram includes two H atoms and one O atom. Answer: Calcium --> Group II --> 2 valence electrons --> charge is +2, so take away all the valence electrons --> go to the inner shell --> 8 electrons. For CO3^2-, neutral CO3 would have two dots and two crosses between one O and the central C atom (a double bond), and one dot and one cross between the other two O atoms and the C. This means there are 8 electrons around the C and the first O, which is fine, but the other two O atoms only have 7 electrons around them, so we add one extra electron to each of them, completing their octets.
