# What is the noble gas shorthand of antimony?

Antimony ($\text{Sb}$ - from Latin Stibium) is located in group 15, row 5 of the periodic table, and has an atomic number of 51.
Since the atom is neutral, $\text{Sb}$'s electron configuration must account for 51 electrons.
$\text{Sb} : 1 {s}^{2} 2 {s}^{2} 2 {p}^{6} 3 {s}^{2} 3 {p}^{6} 4 {s}^{2} 3 {d}^{10} 4 {p}^{6} 5 {s}^{2} 4 {d}^{10} 5 {p}^{3}$
The closest noble gas that comes before $\text{Sb}$ in the periodic table is Krypton, $\text{Kr}$, which means that $\text{Sb}$'s noble gas shorthand notation is
"Sb": ["Kr"]5s^(2)4d^(10)5p^(3)
