electron configuration & orbital practice\nwhich of the following is the correct explanation why the electron configuration below is incorrect?\n1s²2s³2p⁶\nbecause the s sublevel within the 1st energy level exceeded the maximum # of electrons\nbecause the s sublevel within the 2nd energy level exceeded the maximum # of electrons\ni see nothing wrong with it

electron configuration & orbital practice\nwhich of the following is the correct explanation why the electron configuration below is incorrect?\n1s²2s³2p⁶\nbecause the s sublevel within the 1st energy level exceeded the maximum # of electrons\nbecause the s sublevel within the 2nd energy level exceeded the maximum # of electrons\ni see nothing wrong with it

Answer

Brief Explanations:

The s - sublevel in any energy level can hold a maximum of 2 electrons. In the given electron - configuration $1s^{2}2s^{3}2p^{6}$, the $2s$ sublevel has 3 electrons, which exceeds the maximum capacity of 2 electrons for an s - sublevel.

Answer:

Because the s sublevel within the 2nd energy level exceeded the maximum # of electrons
