question 4 (1 point) which is the correct orbital diagram for nitrogen atom (n)? 2s 2p 2s 2p 2s 2p 2s 2p
Answer
Explanation:
Step1: Determine nitrogen's electron - configuration
Nitrogen has an atomic number of 7, so it has 7 electrons. The electron - configuration is $1s^{2}2s^{2}2p^{3}$.
Step2: Apply Hund's rule for 2p orbitals
In the 2p sub - shell (which has 3 orbitals), according to Hund's rule, electrons will first occupy each orbital singly with parallel spins before pairing up. The 2s orbital is filled with a pair of electrons (spin - paired: $\uparrow\downarrow$), and the 2p orbitals have 3 unpaired electrons with parallel spins ($\uparrow$ $\uparrow$ $\uparrow$).
Answer:
The fourth option (with $\uparrow\downarrow$ in 2s and $\uparrow$ $\uparrow$ $\uparrow$ in 2p) is the correct orbital diagram for nitrogen.
