Identify the position of tin (Sn) on the periodic table. Tin is in group 14 (or IV A) of the periodic table.
Recall that the group number for main group elements corresponds to the number of valence electrons. For group 14 elements, the number of valence electrons is 4.
Understand that valence electrons are the electrons in the outermost shell of an atom that participate in chemical bonding.
Confirm that tin, being in group 14, has 4 valence electrons, which is consistent with the general trend for elements in this group.
Therefore, the number of valence electrons for tin (Sn) is 4.
