Answer:
If a sublevel p has 3 electrons, all electrons are in the first p orbital .
Explanation:
According to the rules for establishing the energy level of an element, the sublevel "p" has a capacity for 6 electrons, so a sublevel p with 3 electrons will accept all of those electrons.
An example is nitrogen, with Z = 7, whose electronic level can be written
1s²2s² 2p³
- Two electrons on level 1 sublevel s
- Five electrons on level 2, of which two are in sublevel s and three in sublevel p.
The other options are incorrect:
<em> A and C. It is not possible, because p accepts up to 6 electrons.</em>
<em> D. All sublevels "s" accept up to two electrons, with the exception of hydrogen (z = 1) which has only one electron in the first sublevel s 1s¹.</em>
