Antimony (#"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, #"Sb"#'s electron configuration must account for 51 electrons.

#"Sb":1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(10)4p^(6)5s^(2)4d^(10)5p^(3)#

The closest noble gas that comes before #"Sb"# in the periodic table is Krypton, #"Kr"#, which means that #"Sb"#'s noble gas shorthand notation is

#"Sb": ["Kr"]5s^(2)4d^(10)5p^(3)#
