Question

identify what is wrong with each electron configuration. match the items in the left column to the appropriate blanks in the sentences on the right. there can be no 2d subshell : $1s^2 2s^3 2p^9$. there is a maximum of 6p and 2s electrons : $1s^2 2s^3 2p^6 2d^4$. there can be no 2p subshell : $1s^2 1p^5$. there can be no 1p subshell : $1s^2 2s^2 2p^8 3s^2 3p^1$. there is a maximum of 6p electrons there can be no 3p subshell the 2d subshell should follow the 3s subshell the 2s subshell should follow the 1p subshell the 3p subshell should follow the 4s subshell part b complete previous part(s) part c complete previous part(s) part d complete previous part(s) part e complete previous part(s) provide feedback

Explanation:

Step 1: Analyze \(1s^2 2s^3 2p^9\)

The \(2s\) subshell can hold a maximum of 2 electrons (not 3) and the \(2p\) subshell can hold a maximum of 6 electrons (not 9). So the error is "There is a maximum of 6p and 2s electrons".

Step 2: Analyze \(1s^2 2s^2 2p^6 2d^4\)

The \(n = 2\) shell does not have a \(d\) subshell ( \(d\) subshells start at \(n = 3\) ). So the error is "There can be no \(2d\) subshell".

Step 3: Analyze \(1s^2 1p^5\)

The \(n=1\) shell only has an \(s\) subshell (no \(p\) subshell). So the error is "There can be no \(1p\) subshell".

Step 4: Analyze \(1s^2 2s^2 2p^8 3s^2 3p^1\)

The \(2p\) subshell can hold a maximum of 6 electrons (not 8). So the error is "There is a maximum of 6p electrons".

Answer:

• \(1s^2 2s^3 2p^9\): There is a maximum of 6p and 2s electrons
• \(1s^2 2s^2 2p^6 2d^4\): There can be no \(2d\) subshell
• \(1s^2 1p^5\): There can be no \(1p\) subshell
• \(1s^2 2s^2 2p^8 3s^2 3p^1\): There is a maximum of 6p electrons
