WebNov 4, 2024 · You may assume that the valences of the elements—the number of electrons with which an atom will bond or form—are those that can be derived by looking at the groups (columns) of the periodic table. While these are the most common valences, the real behavior of electrons is less simple. WebCalcium has 20 electrons. (You can see this by looking at the atomic number of Ca on a .) The first 2 go in shell 1, leaving 18 more. 8 more go into shell 2, then 8 in shell 3. Then there are 2 left. This isn’t enough to fill the next shell, which would require 18 more, so we say that Calcium has 3 filled orbitals and 2 free electrons.
