Step 1: Determine the number of electrons in each energy level.
The distribution of electrons in an atom's electron configuration follows the Aufbau principle, which states that electrons occupy the lowest available energy level. The energy levels are labeled with the principal quantum numbers n = 1, 2, 3, 4, ..., and each principal energy level can accommodate a maximum of 2n^2 electrons. For Cobalt (Co), with an atomic number of 27, we can determine the number of electrons in each energy level as follows: - The first energy level (n = 1) can hold up to 2 * 1^2 = 2 electrons. - The second energy level (n = 2) can hold up to 2 * 2^2 = 8 electrons. - The third energy level (n = 3) can hold up to 2 * 3^2 = 18 electrons. - The fourth energy level (n = 4) can hold up to 2 * 4^2 = 32 electrons. Since Cobalt has 27 electrons, the first three energy levels are completely filled, and there is one electron left for the fourth energy level.
Step 2: Write out the electron configuration in spdf notation.
Now that we know the number of electrons in each energy level, we can write out the electron configuration in spdf notation. The s, p, d, and f subshells correspond to the angular momentum quantum numbers l = 0, 1, 2, and 3, respectively. The number of electrons that can be accommodated in each subshell is given by 2(2l + 1). - The 1s subshell can hold up to 2(2 * 0 + 1) = 2 electrons. - The 2s subshell can hold up to 2(2 * 0 + 1) = 2 electrons. - The 2p subshell can hold up to 2(2 * 1 + 1) = 6 electrons. - The 3s subshell can hold up to 2(2 * 0 + 1) = 2 electrons. - The 3p subshell can hold up to 2(2 * 1 + 1) = 6 electrons. - The 3d subshell can hold up to 2(2 * 2 + 1) = 10 electrons. - The 4s subshell can hold up to 2(2 * 0 + 1) = 2 electrons. The electron configuration for Cobalt (Co) is: \boxed{ \text{Cobalt (Co) electron configuration:} \ 1s^2 \ 2s^2 \ 2p^6 \ 3s^2 \ 3p^6 \ 3d^7 \ 4s^1 }
Final Answer
The electron configuration for Cobalt (Co) is 1s^2 2s^2 2p^6 3s^2 3p^6 3d^7 4s^1 in spdf notation.
