The electronic configuration of tin is [Kr]4d¹⁰5s²5p². Written out in full, this is 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p². It has two common / stable cations:

Sn²⁺ has electronic structure [Kr]4d¹⁰5s². Written out in full, this is 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s².

Sn⁴⁺ has electronic structure [Kr]4d¹⁰. Written out in full, this is 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰.

Representations are sometimes written showing the subshells in order of increasing energy, such as [Kr]5s²4d¹⁰5p², but placing them in order of increasing shells - and within that, subshells - is the standard representation method.
