Electron Configuration and Properties of Tin

This video tutorial explains how to write the electron configuration for tin (Sn) and its ions, Sn2+ and Sn4+. It begins by identifying tin's atomic number and the number of electrons. Two methods for writing electron configurations are discussed: using a table and dividing the periodic table into orbital blocks. The video provides a detailed walkthrough of tin's electron configuration, including a condensed notation using krypton as a reference. It also covers the electron configurations for Sn2+ and Sn4+ ions, explaining the loss of valence electrons. The tutorial concludes with notes on the order of electron configuration and ionization.
