WebIn this case, 2+2+6+2+6+2+10+6+2+1= 39 and Z=39, so the answer is correct. A slightly more complicated example is the electron configuration of bismuth (symbolized Bi, with Z = 83). The periodic table gives the following electron configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p65s2 4d10 5p6 6s2 4f14 5d10 6p3. WebSep 6, 2024 · The maximum number of electrons that can fill each shell is: two in the first shell, eight in the second shell, eight in the third shell. Calcium, the 20 th element, has two further electrons that go in the fourth shell. In the shorthand notation for electron configuration, the number of electrons in each shell can be written rather than drawn ...
