Question #008eb

Answer 1

Choices a, b, and d are not written properly
and,
there is nothing wrong with choice c

Explanation:

Choice a, b, and d are all not correct valence electron configurations when writing the valence electron shorthand.

Choice a is incorrect because for `n=2, l=0` there are only two orbital about the (`s`) subshell.

Choice b is incorrect because two "`2s^2`" orbital are written and the next two electron would instead fill the `n=2,l=1` (`p`) shell and its 3 orbital.

Choice d is incorrect because for `n=1`, `l` can only `=0`. Remember that `l` can have value between `0 -> n-1`.

In other words, there is no such thing as a "`1p`" orbital.
