Question

Ap sublevel has 3 electrons. How should they be arranged

A.)Two electrons in the first p orbital and one in the second p orbital
B.)All electrons are in the first orbital
C.)One electron in each p orbital
D.)One electron in the first shorbital and 2 in the second

Answer 1

If a sublevel p has 3 electrons, all electrons are in the first p orbital .

Step-by-step 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:

A and C. It is not possible, because p accepts up to 6 electrons.

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.
