* Because a (-) is adding and (+) is subtracting.. so since this problem is a (-2) then you will add it to the total found.. hope this helps!
There are a total of 22 electrons in the CO3 2- ion. This consists of 6 electrons from carbon (C) and 8 electrons from each of the three oxygen (O) atoms, along with the additional 2 electrons to account for the overall 2- charge of the ion.
Zinc has 2 valence electrons.
Calcium has 2 valence electrons, like all Group 2 elements.

Alkaline earths have 2 valence electrons.
The carbonate ion, CO3 2-, has a total of 24 valence electrons. This is because there are three oxygen atoms, each contributing 6 valence electrons, and a charge of 2- indicates the addition of 2 electrons to account for the overall charge on the ion.
