Finally, the elements in the section usually printed below the rest of the table make up what is called the f-block. The elements in groups 13 through 18 have electron configurations that end with a p-orbital so those elements are referred to as the p-block. These groups make up the d-block of the periodic table. For all the elements in groups 3 through 12 the electron configurations end with a d-orbital. A similar result is found for the alkaline earth metals in group 2 (Be, Mg, Ca, etc.) Each of those elements has an electron configuration ending in s 2.įor this reason, the first two columns in the periodic table are called the s-block. Within a group we found that the electron configurations always ended with the same type of orbital with the same number of electrons.įor example, in group 1 (the alkali metals) the electron configurations are: Li 1s 2 2s 1 Na 1s 2 2s 2 2p 6 3s 1 K 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 Rb 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 1 Cs 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 1 Each of these elements has an electron configuration that ends with an s-orbital containing one electron: 2s 1, 3s 1, 4s 1, etc. In this activity we practiced writing the ground state electron configuration for elements in the same column, or group, in the periodic table. Your changes list should be typed and handed in to earn credit for this assignment. If you notice something that this summary leaves out then please bring it to the attention of your teacher. For homework use your comparison to write down all changes you would need to make to your summary to make it accurate and complete. Compare this summary to the one your teacher asked you to write.
