Write the electron configuration and electron orbital diagram for the following element:
Sulfur (Z = 16)
A
B
C
D
E
Verified step by step guidance1
Identify the atomic number of sulfur, which is 16. This means sulfur has 16 electrons.
Write the electron configuration by filling the orbitals in order of increasing energy: 1s, 2s, 2p, 3s, and 3p.
Start filling the orbitals: 1s can hold 2 electrons, so write 1s2.
Next, fill the 2s orbital with 2 electrons: 2s2.
Continue with the 2p orbital, which can hold 6 electrons: 2p6. Then fill the 3s orbital with 2 electrons: 3s2. Finally, place the remaining 4 electrons in the 3p orbital: 3p4.
