This last bit about the formation of the ions is clearly unsatisfactory. We say that the 4s orbitals have a lower energy than the 3d, and so the 4s orbitals are filled first.

Rememberthat the “s” sub-levels start with 1s, the “p” sub-levels start with 2p, the“d” sub-levels start with 3d, and the “f” sub-levels start with 4f. The“gotchas” are: · The 3d sub-level is in row 4, right after 4s. · The 4f sub-level is in row 6, right after 6s. Writing Electron Configurations.

What similarities do you observe among the first six given samples?2. 👍 Correct answer to the question 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 3s^2 - e-eduanswers.com (d) {eq}1s^2 2s^2 2p^6 3s^2 3p^6 3d^{10} 4s^2 4p^3 {/eq} Electronic Configuration: The electronic configuration is specific for each atom in the periodic table. The arrow goes through 1s first, then 2s, then 2p & 3s, then 3p & 4s, then 3d, 4p, & 5s, and so on. Some people find it easier to use the periodic table as the “road map”: As you move through the elements in order by atomic number, you are moving through the sub-levels from lowest to highest energy. ex 4s fills before 3d, because 4s has less energy than 3d.

It must fill first. Electrons fill the sublevels in energy order 1s 2s 2p 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p. If we add the number of electrons that each sublevel holds it looks like this: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 2 4f 14 5d 10 6p 6 7s 2 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 10 4p 6 5s 2 4d 10 5p 6 6s 2 4f 14 5d 10 6p 6 7s 2 5f 14 6d 10 7p 6 Alternatively, write the symbol for the noble gas before an element (radon, in this case), and just add the extra information: 2s: 1 2p: 0 3s: 0 3p: 0 4s: 0 3d: 0 4p: 0 5s: 0 Hope that helped.
