Question

what is the electron configuration of antimony? kr5s²5d¹⁰5p⁶ kr5s²4d¹⁰5p³ xe5s²4d¹⁰5p⁶ xe5s²4d¹⁰5p²

Explanation:

Antimony has an atomic number of 51. Krypton (\(Kr\)) has an atomic number of 36. After \(Kr\), the filling order is \(5s\), then \(4d\), then \(5p\). The \(5s\) sub - shell can hold 2 electrons, the \(4d\) sub - shell can hold 10 electrons, and for antimony (\(Sb\)), the \(5p\) sub - shell has 3 electrons.

Answer:

$$ \text{[Kr]}5s^{2}4d^{10}5p^{3} $$
