zirconium, hafnium, and rutherfordium are all in the same family as titanium. To help you along your way, I'll let you in on a little secret:

An element's "family" is a fancy way of saying the "column" (vertical row) on the Periodic Table of elements. So anything in that column is in the same family as that element.

The reason it is organized this way is because all of the elements in that family have the same number of valance electrons (save for helium, which only has 2 valance electrons, and the rest of the noble gas family have 8). Valance electrons are the electrons in the outer most electron orbitals.
