Naming and Properties of SnSe2

The video tutorial explains how to name the compound SnSe2. It starts by identifying Sn as a transition metal and Se as a nonmetal, treating the compound as ionic. Sn is named as tin, and Se is named as selenide, with the 'ium' ending replaced by 'ide'. The oxidation numbers are determined, with Se having a 2- charge and Sn needing a 4+ charge to balance. The final name is given as tin(IV) selenide, with the oxidation state of tin indicated in parentheses.
