What Are The Steps For Determining Electron Configuration For Samarium?
To determine the electron configuration for Samarium, you need to follow a specific order when filling orbitals with electrons. The atomic number of Samarium is 62, so its electron configuration is written as 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d10 5s2 5p6 4f6 6s2.
When it comes to determining the electron configuration for Samarium, there are a few easy steps that you can follow. It is important to understand each step to write out the electron configuration correctly. Here are the steps you need to follow to determine the electron configuration for Samarium:
Step 1: Find The Atomic Number Of Samarium
The first step in determining a samarium’s electron configuration is to find its atomic number. Samarium’s atomic number is 62, which means it has 62 electrons in total.
Step 2: Write The Configuration For The Previous Noble Gas
The next step is to write the configuration for the previous noble gas. In Samarium’s case, the previous noble gas is Xenon (atomic number 54). The electron configuration for Xenon is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. You can write this configuration using shorthand notation as [Xe].
Step 3: Write The Subshell Configuration For The Remaining Electrons
After writing the previous noble gas configuration, you must write the subshell configuration for the remaining electrons in Samarium. Samarium has 62 electrons, and the configuration for Xenon accounts for 54 of those electrons. This means there are 8 electrons left, which can be written out using the subshell configuration notation.
Step 4: Complete The Configuration With Remaining Electrons
The final step is to complete the configuration with the remaining electrons using the subshell configuration notation. Samarium has 8 electrons left, which can be written as 5d1 6s2 4f5. When you combine this subshell notation with the previous noble gas notation [Xe], you get the full electron configuration for Samarium, which is [Xe] 4f5 6s2 5d1. In conclusion, determining the electron configuration for Samarium is straightforward if you follow the steps listed above. It involves finding the atomic number, writing the configuration for the previous noble gas, writing the subshell configuration for the remaining electrons, and completing the configuration with the remaining electrons.
