Question

1. drag and drop the answers for the orbital diagram for nitrogen. refer to the periodic table. electrons in box diagram 1s 2s 2p 3s 3p choices two arrows (up and down), one arrow (up)

Explanation:

Step1: Find nitrogen's electron count

Nitrogen (N) has an atomic number of 7, so it has 7 electrons total.

Step2: Fill orbitals by Aufbau principle

Fill lower energy orbitals first: 1s holds max 2 electrons, 2s holds max 2 electrons, 2p holds max 6 electrons.

• 1s: $\uparrow\downarrow$ (2 electrons)
• 2s: $\uparrow\downarrow$ (2 electrons, total 4 so far)
• 2p: 3 remaining electrons, fill singly (Hund's rule) → $\uparrow$ $\uparrow$ $\uparrow$

Step3: Ignore higher energy orbitals

3s and 3p are unfilled for nitrogen, so leave empty.

Answer:

1s: $\boldsymbol{\uparrow\downarrow}$
2s: $\boldsymbol{\uparrow\downarrow}$
2p: $\boldsymbol{\uparrow}$ $\boldsymbol{\uparrow}$ $\boldsymbol{\uparrow}$
3s: (empty)
3p: (empty)
