Final answer:
Among the elements Sn, Ge, Ti, and Si, Ti (Titanium) is the element that belongs to a different group in the period table. Sn, Ge, and Si belong to group 14 (Carbon group), while Ti belongs to group 4 (Titanium group).
Step-by-step explanation:
The question asks you to identify the element from a different periodic table group among Sn (Tin), Ge (Germanium), Ti (Titanium), and Si (Silicon). Sn, Ge, and Si are from group 14 of the periodic table, also known as the Carbon group. On the other hand, Ti is from group 4, also known as the Titanium group. So, the element that is from a different periodic table group than the others is Titanium (Ti).
