An atom that had satisfied the octet rule will have which of the following valence electron configurations? a) a full s orbital b) a full p orbital c) a full s orbital d) both full s orbital and full p orbital

The s orbital can hold up to two electrons while the p orbital can hold up to six electrons.
An atoms satisfying the octet rule means that this atom has eight electrons in its outermost energy level (which is the maximum number of electrons that can be found in a single level and makes the atom stable).
For this to happen, two electrons must occupy the s orbital and 6 electrons must occupy the p orbital. This makes a total of eight electrons.

Therefore, the right choice is:
d) both full s orbital and full p orbital
