WebCalcium 20 40.078 Glossary Group A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Period A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right. Block 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. WebFor instance, the ground state electronic configuration of calcium (Z=20) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2. The calcium ion (Ca 2+ ), however, has two electrons less. Hence, the electron configuration for Ca 2+ is 1s 2 2s 2 2p 6 3s 2 3p 6. Since we need to take away two electrons, we first remove electrons from the outermost shell (n=4). irs efile software providers
