how many unpeeled electrons are in this configuration 1s2 2s2 2p6 3s2 3p3
unpeeled?, or unpaired? the three in 3p3
To determine the number of unpeeled electrons in the given electron configuration (1s2 2s2 2p6 3s2 3p3), you need to look at the last energy level (n) and count the electrons present in the highest subshell.
In this case, the last energy level is the third energy level (n=3), and the highest subshell in the third energy level is the 3p subshell.
The configuration 3p3 tells us that there are 3 electrons in the 3p subshell. These 3 electrons are considered unpeeled since they are not fully paired with another electron in the same orbital.
Therefore, the number of unpeeled electrons in this configuration is 3.
