Question

draw the orbital diagram for each of the foll oxygen energy

Explanation:

Step1: Determine oxygen's atomic number

Oxygen has an atomic number of 8, so it has 8 electrons.

Step2: Fill electrons according to Aufbau principle

Electrons fill lower - energy orbitals first. The 1s orbital fills first (2 electrons), then the 2s orbital (2 electrons), and then the 2p orbital.

Step3: Apply Hund's rule in 2p orbital

In the 2p orbital (which has 3 sub - orbitals), the last 4 electrons are distributed such that first, each of the 3 sub - orbitals gets 1 electron (with parallel spins), and then the fourth electron pairs up with one of them.

The orbital diagram for oxygen:
1s: $\uparrow\downarrow$
2s: $\uparrow\downarrow$
2p: $\uparrow\downarrow$ $\uparrow$ $\uparrow$

Answer:

1s: $\uparrow\downarrow$
2s: $\uparrow\downarrow$
2p: $\uparrow\downarrow$ $\uparrow$ $\uparrow$
